TSC Promotion Interviews Begin Next Week: Full Scoring Breakdown for 34,016 Vacancies
The countdown to one of the biggest career-progression exercises in Kenya’s teaching service is now in its final, decisive stretch.
The Teachers Service Commission (TSC) advertised 34,016 promotion vacancies for the 2026/2027 financial year, covering primary schools, secondary schools, Teacher Training Colleges (TTCs) and the cadre of Curriculum Support Officers (CSOs).
The application window closed on 10th August 2026, and the exercise has now moved into its most anxiety-inducing phase: shortlisting, interview invitations, and the interviews themselves.
Since Monday, 31st August 2026, Regional, County and Sub-County Directors have been sending out invitation messages — many teachers are already reporting SMS notifications inviting them to appear before selection panels.
This invitation window will run until Friday, 11th September 2026. Hard on its heels, actual interviews begin the following week, starting with primary school teachers and later moving to post-primary and CSO cadres.
For thousands of teachers who have waited years — sometimes over a decade — for a shot at the next grade, the single most important question right now is simple: how exactly will I be scored? This article walks through the full interview timeline and breaks down, cadre by cadre, the scoring framework TSC has published for this promotion cycle, drawing on Circular No. 13/2026 and the accompanying grade-specific scoring guides.
1. The Big Picture: What This Promotion Cycle Involves
The 34,016 vacancies represent one of the largest promotion drives TSC has undertaken in recent years, running alongside a separate recruitment exercise for new teachers.
The promotions span virtually every competitive grade in the teaching service — from classroom teachers moving up job groups, to Senior Teachers, Deputy Headteachers, Headteachers, Senior Masters, Deputy Principals, Principals, Chief Principals, Senior Lecturers in TTCs, and Curriculum Support Officers at various levels.
To standardise what has historically been a process prone to disputes and allegations of favouritism, TSC developed what it calls a standardised scoring guide, intended to ensure that every shortlisted candidate is evaluated on the same objective criteria regardless of which panel interviews them.
The Commission has been explicit that these guidelines remain valid until 30th June 2027 and apply uniformly to all teachers employed by TSC who are competing for the advertised grades.
Applications for this cycle were submitted exclusively through the Teachers Online Services (TOS) platform, with TSC ruling out manual or physical submissions entirely.
Shortlisting was done at a ratio of three candidates for every one advertised position, meaning that for every vacancy, up to three eligible applicants have been invited to compete at interview.
This 1:3 ratio is important context: making the shortlist is already a significant filter, and it means that even after shortlisting, roughly two out of three shortlisted candidates for any given post may still miss out at the interview stage.
That is precisely why understanding the scoring mechanics matters so much — the interview score, not the application itself, is what will ultimately decide who gets promoted.
2. The Interview Timeline: What Is Happening and When
Teachers preparing for this exercise need to keep three separate dates firmly in mind, because different cadres are handled on different tracks and by different panels.
Shortlisting invitations: 31st August – 11th September 2026. This is the stage the country is currently in. Regional, County and Sub-County Directors are responsible for identifying shortlisted candidates and notifying them, largely via SMS, of their interview date, time and venue.
If you have not yet received an SMS and you applied for a promotion in this cycle, it does not necessarily mean you have missed out — the invitation window is still open until 11th September, so notifications will continue to go out in batches depending on your region, grade and interview schedule.
Primary school teacher interviews: 8th – 15th September 2026 (6 days). Primary school teachers are the first cadre to face panels in this cycle. These interviews will be conducted at the regional and county levels by field directors, and the process has been designed to prioritise what TSC refers to as “foundational promotional tiers” — essentially the entry and mid-level competitive grades that form the backbone of the primary school staffing structure, such as movement from one job group to the next, and headship positions like Deputy Headteacher and Headteacher.
Post-primary and CSO interviews: 17th – 25th September 2026 (7 days). Once the primary school interviews conclude, attention shifts to secondary school teachers, TTC lecturers, and Curriculum Support Officers.
This second phase is spearheaded by the Director of Staffing, working alongside regional, county and sub-county directors. It covers a wider range of grades and roles — from classroom teacher promotions in secondary schools through to Senior Master, Deputy Principal, Principal, Senior Lecturer, and CSO positions at sub-county, county and regional level.
Notice the short but deliberate gap between the two phases — 15th to 17th September — which gives directors and panel members time to reset, reallocate personnel, and prepare for the different scoring guides that apply to post-primary and CSO grades, which are structured differently from the primary school scoring sheets.
Throughout both phases, TSC has committed to giving shortlisted candidates a minimum notice period before their scheduled interview date, so that no teacher is asked to appear without reasonable time to prepare and travel to the venue.
3. Who Sits on the Interview Panels?
Understanding who is scoring you is almost as important as understanding what they are scoring. TSC has structured its panels around three tiers, matched to the seniority of the position being filled.
Sub-County Panels handle interviews for primary school teachers, including Headteachers and Deputy Headteachers at that level. This is the most localised tier and is where the bulk of primary promotion interviews will take place during the 8th–15th September window.
County Selection Panels oversee interviews for post-primary school teachers, including Deputy Principals. These panels sit at the county level and are central to the second phase of interviews running from 17th to 25th September.
Regional Panels handle the most senior positions — Principals, TTC administrators, and Curriculum Support Officers — reflecting the fact that these roles typically carry regional or even national significance.
Each panel is composed of a Chairperson who oversees proceedings and ensures adherence to policy, a Commission Secretary representative who participates in scoring and maintains interview records, and a Director’s representative who supports the scoring process and quality assurance.
Where a panel member is unavailable, TSC allows a suitably ranked officer to stand in. Every panel member is required to declare any actual, potential or perceived conflict of interest before the interviews begin — a safeguard aimed at protecting the integrity of the exercise.
4. The Core Principles Behind the Scoring System
Before diving into the actual marks, it helps to understand the five broad pillars that TSC says underpin every scoring guide, regardless of cadre or grade:
1. Academic Qualifications — higher academic and professional qualifications attract higher marks, reflecting a teacher’s investment in continuous professional growth.
2. Acting or Administrative Capacity — teachers currently serving in acting or performing roles, such as Head of Institution, Deputy Head, or Senior Master/Senior Teacher, earn additional marks for that responsibility.
3. Length of Stay in the Current Grade — teachers who have remained longer in their present grade without a promotion earn progressively higher scores, recognising stagnation and rewarding patience and continuity.
3. Teacher Performance Appraisal and Development (TPAD) — the average TPAD rating over the previous three years is factored in, rewarding consistently strong classroom and professional performance. Notably, TSC has clarified that this criterion does not apply to Curriculum Support Officers, since CSOs are not appraised through the standard classroom-based TPAD tool in the same way.
4. Seniority, Experience and Professional Contribution — years of service in the teaching profession, together with involvement in national assignments such as KNEC examination work, KICD curriculum development, CBC training, CEMASTEA science and mathematics programmes, MOE task forces, KISE special-needs work, KEMI management training, or TSC’s own Teacher Induction, Mentorship, Coaching and Curriculum-based competency (TIMEC) programme, all attract additional marks.
On top of these five pillars, most scoring guides also allocate a portion of marks to age and to co-curricular participation (sports, music, drama and similar activities at sub-county, county, regional, national or international level), though the weighting of these two factors varies significantly depending on the grade being competed for.
Every candidate is assessed out of a maximum of 100 marks, and it is the interview score — not the application, and not seniority alone — that TSC says will be the primary determinant of who is promoted.
5. The Scoring Breakdown by Cadre
This is where things get specific. TSC has issued grade-specific scoring guides rather than one single sheet for everyone, because the weighting of each pillar shifts depending on whether you are a classroom teacher, a deputy headteacher, a principal, or a senior lecturer.
Below are the published breakdowns for several major cadres. If your specific grade is not listed here, expect a similar structure, but always confirm the exact scoring sheet with your sub-county or county director, since minor variations exist across the annexed guides.
A. Classroom Teachers and Senior Lecturer II (Non-Administrative Grades)
For teachers competing purely on classroom-based promotion — moving up a job group without taking on headship or principalship — the guide leans heavily on how long you have stayed in your current grade and your age, rather than paper qualifications.
- Length of stay in the current job group: up to 50 marks — by far the single largest component. A teacher with exactly three years in the grade earns around 10 marks, with the score rising steadily the longer a teacher has remained without promotion, up to the maximum for the longest-serving candidates.
- Age: up to 30 marks — teachers aged 57 and above receive the full 30 marks, those aged 52–56 receive 25, ages 47–51 receive 20, ages 42–46 receive 15, and teachers aged 41 and below receive 10 marks.
- TPAD performance: up to 10 marks — based on the average appraisal rating for the previous three years. A rating of 81% and above earns the full 10 marks, 61–80% earns 8 marks, 41–60% earns 6 marks, 21–40% earns 4 marks, and 1–20% earns 2 marks.
- Academic qualifications: up to 5 marks — doctorate holders top this category, with master’s and bachelor’s degree holders scoring progressively fewer marks.
- Co-curricular activities: up to 5 marks — international-level participation earns the full 5 marks, national level 4, regional 3, county 2, and sub-county 1.
Add these together and you arrive at the full 100 marks. The clear message for classroom teachers is that time served in your current grade and your age will do more to move your total score than an extra certificate or diploma will.
B. Deputy Headteacher I (and Similar Headship-Track Grades)
Here the picture shifts because administrative or acting responsibility enters the equation and is combined with length of stay to form the single biggest block of marks.
- Administrative responsibility and length of stay in the current grade (combined): up to 55 marks, broken down further as:
- Administrative responsibility (time spent acting as Headteacher or in a similar leadership capacity): up to 25 marks, with teachers who have performed the role for eight years or more earning the full 25, and the score reducing progressively for shorter periods.
- Length of stay in the current grade on its own: up to 30 marks, again rewarding the longest-serving candidates most generously.
- Age: up to 25 marks.
- TPAD performance: up to 10 marks, using the same three-year average banding described above.
- Academic and professional qualifications: up to 3 marks.
- Professional assignments (KNEC, KICD, and similar bodies): up to 2 marks.
- Co-curricular activities: up to 5 marks.
Notice how, compared to the classroom-teacher scoring guide, paper qualifications shrink even further in importance (down to just 3 marks) while demonstrated leadership experience — actually having acted in the role — becomes central to the score.
C. Chief Principal and Senior Principal (Grades D5 and D4)
At the most senior end of the school leadership ladder, the scoring guide again places length of service at the very top, but with a slightly different distribution.
- Length of stay in the current grade: up to 45 marks — the highest-weighted single factor for this grade. Teachers who have remained in the grade for eight years or more receive the full 45 marks, with those who have stayed only three years receiving around 20 marks, and the score scaling between these two points.
- Age: up to 30 marks — following the same age bands used for classroom teachers, with 57 years and above attracting the maximum.
- TPAD performance: up to 10 marks, calculated the same way as other cadres.
- Academic qualifications: up to 5 marks.
- Professional assignments (KNEC, KICD, CBC, CEMASTEA, and other TSC-run programmes): up to 5 marks.
- Co-curricular activities: up to 5 marks.
Together these add up to 100 marks, with length of stay and age alone accounting for the vast majority of the available score — a clear signal that at this level, TSC is rewarding sustained, long-term service in the grade above almost anything else.
D. Principal and Deputy Principal Grades (D3, D2, D1)
For Principals and Deputy Principals across the three competitive grades — Deputy Principal I (D3), Deputy Principal II (D2), and Deputy Principal III (D1) — administrative experience takes clear priority, alongside qualifications and appraisal performance.
- Administrative responsibility: up to 25 marks — candidates who have served in an acting Principal or Deputy Principal capacity score highest, with those who have carried the responsibility for eight years or more earning the full 25 marks and shorter periods earning progressively less.
- Academic and professional qualifications: up to 3 marks — a PhD earns 3 marks, a master’s degree earns 2 marks, and a bachelor’s degree earns 1 mark; teachers who upgraded to a bachelor’s degree after joining the service are also credited with 1 mark under this category.
- TPAD performance: up to 10 marks, again based on the three-year average rating.
- The remaining marks are distributed across length of stay in the current grade, age, and co-curricular participation, broadly mirroring the structure used for other administrative cadres, though the exact split can vary slightly by grade — candidates should confirm the precise annexed sheet for their specific post with their county director.
The consistent theme across Principal and Deputy Principal grades is that demonstrated administrative track record — actually having acted in the role — carries substantial weight, second only to length of stay considerations once all sub-components are combined.
E. Curriculum Support Officers (CSOs)
CSOs are treated somewhat differently because their day-to-day role does not involve classroom teaching in the same way as other cadres, and TSC has expressly stated that the standard TPAD criterion does not apply to this group.
Instead, CSO scoring leans more heavily on length of service, seniority, professional assignments and administrative or supervisory experience, without the 10-mark TPAD component that other cadres carry. CSO interviews fall under the second phase of this exercise, running from 17th to 25th September 2026, and are conducted through a combination of regional, county and sub-county panels depending on the specific level of the CSO post being competed for.
6. Tie-Breakers and the Final Selection Process
Interview scores alone do not automatically translate into a promotion letter. Once panels have scored every candidate, TSC’s Board takes over oversight of the wider process before any list is finalised.
Selection at this final stage is based strictly on merit as determined by the interview scores, but it is also required to comply with constitutional principles, meaning panels and the Board must have regard to:
- Gender representation — ensuring promotions do not skew disproportionately toward one gender where qualified candidates of both genders are available.
- Disability inclusion — ensuring teachers living with disabilities are fairly considered and not disadvantaged in the final outcome.
- Regional diversity — ensuring promotions are not concentrated in particular regions or counties at the expense of others.
Where candidates end up tied on aggregate score — which is not unusual given how structured and banded the scoring criteria are — panels apply a defined set of preference criteria to break the tie.
The clearest of these is length of time since graduation, which can itself carry a weighting of marks in some scoring sheets and is typically the first tiebreaker applied, with the candidate who graduated furthest back in time given priority.
In effect, this means that between two candidates who are otherwise dead level on every other score, the one who has been out of college or university longer is likely to edge ahead.
Because of these tie-breaking and inclusion safeguards, it is entirely possible for a candidate with a marginally lower raw score to still be selected over one with a slightly higher score, if doing so helps the Commission meet its constitutional obligations on gender, disability or regional balance.
This is a nuance worth keeping in mind so that candidates do not assume the exercise is a purely mechanical, highest-score-wins process — it is merit-based, but merit is applied within a framework that also has to answer to fairness across the whole teaching service.
Once the Board has approved the final list, successful candidates will be published through TSC’s official website, and heads and deputy heads of institutions will subsequently be posted to schools with available vacancies.
TSC has indicated that a full exit report on how the exercise was conducted will be compiled and submitted to the Board in the new year, underscoring how seriously the Commission is treating accountability for this cycle.
7. How Teachers Should Prepare Between Now and Their Interview Date
Given everything above, teachers awaiting their invitation or already holding one should focus their preparation on a few practical steps rather than generic interview coaching.
Confirm your exact score inputs before you walk in. Work out, on paper, roughly how many marks you expect to score under length of stay in your current grade, your age band, your three-year average TPAD rating, your highest qualification, and any professional assignments or co-curricular involvement you can document. Knowing your own likely score gives you realistic expectations and helps you identify which documents to carry.
Carry every supporting document. Since qualifications, TPAD ratings, acting appointment letters, and evidence of professional assignments all translate directly into marks, missing or unverifiable documentation can cost you points that have nothing to do with how well you answer questions in the room. Certificates, appointment letters for acting roles, TPAD appraisal printouts, and letters confirming participation in KNEC, KICD, CBC, CEMASTEA, TIMEC or similar assignments should all be organised and ready.
Understand which scoring sheet applies to you. Because the weighting differs meaningfully between a classroom teacher’s scoring guide and a Deputy Headteacher’s or Principal’s guide, candidates should not assume the general framework applies uniformly. If in doubt, sub-county, county or regional directors’ offices can confirm which annexed scoring guide will be used for your specific position.
Be realistic about what you cannot change. Age and length of stay in your current grade are fixed by the time you walk into the interview room — no amount of preparation changes them. What you can influence in the short term is how clearly you present your acting experience, professional contributions, and any recent TPAD performance, so make sure these are well documented and easy for the panel to verify quickly.
Avoid brokers and unofficial “guarantees.” TSC has been explicit and public in warning teachers against paying brokers or middlemen who claim they can influence promotion outcomes. The Commission has stated that the entire promotion process is free of charge, and that any teacher found canvassing for votes or attempting to unduly influence a panel risks automatic disqualification from the exercise. Given how structured and points-based the scoring system is, there is genuinely little room for informal influence to override a documented score — treat any such offer as a red flag.
8. Key Dates at a Glance
To close, here is the full sequence of what has happened and what is coming, condensed into one reference point:
- 10th August 2026 — Application window for the 34,016 advertised promotion vacancies closed.
- 31st August – 11th September 2026 — Regional, County and Sub-County Directors issue shortlisting and interview invitations, largely via SMS.
- 8th – 15th September 2026 (6 days) — Primary school teacher interviews, conducted at regional and county level by field directors, prioritising foundational promotional tiers.
- 17th – 25th September 2026 (7 days) — Post-primary (secondary school and TTC) and CSO interviews, spearheaded by the Director of Staffing together with regional, county and sub-county directors.
- After interviews conclude — Panel scores are compiled, the Commission’s Board reviews and approves the final list with regard to gender, disability and regional balance, and successful candidates are published on TSC’s official website ahead of posting to their new stations.
Final Word
This promotion cycle is unusually transparent by TSC’s own historical standards, largely because the Commission has published detailed, grade-specific scoring guides rather than leaving panels to exercise unstructured discretion.
For the individual teacher, that transparency cuts both ways: it removes much of the mystery around how decisions will be made, but it also means your outcome is now largely a function of documentable facts — your length of stay in grade, your age, your TPAD record, your qualifications, and your professional contributions — rather than how persuasively you perform in the interview chair alone.
Teachers who have already received their SMS invitations should treat the coming days as an administrative sprint: gather documents, verify your figures against the relevant scoring sheet for your grade, and arrive at your panel on time and fully prepared.
Those still waiting should keep checking their phones through to 11th September, while using the time productively to get their paperwork in order for whichever week — 8th to 15th or 17th to 25th September — their cadre falls into.
