The Teachers Service Commission (TSC) has revised the promotional service requirement: teachers now need two years in their current grade instead of three to apply for select leadership posts. This change affects promotions to Deputy Principal III, Senior Master II, and Deputy Headteacher II and opens opportunities for many teachers — especially those in hardship and ASAL areas — who were previously excluded by the stricter rule.
Key Takeaways
- Main change: Minimum service in current grade lowered from three years to two years for selected re-advertised vacancies.
- Positions affected: Deputy Principal III (132 posts), Senior Master II (29 posts), Deputy Headteacher II (1,470 posts).
- Deadline: Apply online via the TSC portal by midnight on Monday, 14 September 2026.
- Requirements still in place: Satisfactory TPAD ratings and evidence of supervision, mentorship and professional support.
TSC promotion requirements: background
The change comes after a large promotional exercise that advertised 34,016 vacancies closed on 10 August 2026. Many capable teachers were ineligible under the three-year rule and could not apply, especially teachers in ASAL and other hardship areas. TSC re-advertised selected vacancies and reduced the tenure requirement to ensure enough qualified applicants and to fill leadership gaps in schools.
Which posts are re-advertised and who is eligible?
The re-advertisement covers three grades with revised tenure rules:
- Advert No. 108/2026 – Deputy Principal III (T-Scale 11, D1): 132 posts. Candidates must have served as Senior Master III (T-Scale 10, C5) for a minimum of two years.
- Advert No. 109/2026 – Senior Master II (T-Scale 11, D1): 29 posts. Candidates must have served as Senior Master III or Senior Master III – JSS for at least two years.
- Advert No. 110/2026 – Deputy Headteacher II (T-Scale 9, C4): 1,470 posts. Primary teachers serving as Senior Teacher I (T-Scale 8, C3) are now eligible after two years in grade.
Core eligibility and selection criteria
Although the tenure requirement is reduced, these key selection criteria remain mandatory:
- Satisfactory performance appraisal (TPAD) — consistent satisfactory ratings are essential.
- Demonstrated leadership: experience supervising, mentoring and supporting other teachers.
- Additional vetting: any other requirements deemed necessary by the Commission may apply.
Why the change matters
Reducing the waiting period from three years to two removes a timing barrier that had excluded many qualified teachers. The adjustment:
- Creates a larger pool of applicants and helps fill leadership vacancies faster.
- Levels the playing field for teachers in remote and hardship areas who face irregular career progression.
- Signals a more responsive approach by the Commission to real-world outcomes.
Practical steps for applicants
If you now qualify under the two-year rule, follow these steps to strengthen your application:
- Confirm your TPAD rating is up to date and satisfactory.
- Document mentorship and supervisory duties with clear examples.
- Prepare certified copies of required documents and update your profile on the TSC portal.
- Submit your application early — the portal often experiences high traffic close to the deadline.
How to apply
Applications must be submitted online through the TSC portal at www.teachersonline.go.ke. Manual or emailed applications are not accepted. Note that teachers who already applied successfully for these specific posts under the earlier advertisement do not need to reapply.
Resources and preparation links
Teachers preparing for interviews or seeking teaching resources can use free practice and curriculum materials. For example, access subject practice materials and mock exams to refresh classroom and leadership knowledge:
- CBC practice exams and resources — helpful for primary and junior secondary pedagogical refreshers.
- KCPE past papers and revision exams — useful for primary teachers preparing leadership plans and assessment strategies.
- Grade-specific schemes of work — use these to demonstrate curriculum leadership in your application and interview.
Final notes for applicants
This reduction in the service requirement is a targeted, temporary adjustment for the listed re-advertised posts. Meeting the two-year tenure rule does not guarantee promotion — strong performance records, clear leadership evidence, and timely, complete applications remain crucial. Teachers in ASAL and hardship areas should take advantage of this opportunity to apply and demonstrate readiness for school leadership.
