The Curriculum Based Establishment (CBE) and timetabling guidelines set clear rules for how many lessons schools must offer, how long lessons should run, and how many teachers a school needs for effective curriculum delivery. This article explains the new CBE timetabling rules, lesson allocations by level, how to compute teacher establishment, and practical steps schools should take to comply.
Key Takeaways
- CBE timetabling defines lesson counts, lesson lengths, reporting times and health breaks for each level.
- Primary and junior schools use fixed weekly lesson totals and specified lesson durations to ensure balanced coverage.
- CBE calculations combine lessons-per-subject and shortfalls from administrative duties to determine teacher numbers.
- Special needs and pre-vocational settings use teacher–learner ratios based on disability type and severity.
Understanding Curriculum Based Establishment (CBE)
CBE is the number of teachers a school needs to deliver the approved curriculum effectively. The process starts with the school applying to the Sub County Director of Education, followed by verification of learning areas, lessons and enrolment. Once computed and approved, the CBE is forwarded to the Teachers Service Commission for teacher allocation.
Timetabling rules for regular schools
The guidelines require every school to form a timetabling committee and to display the approved timetable publicly. Committees must avoid placing learning areas with similar skills back-to-back and should schedule creative, psychomotor and physical activities before breaks.
Pre-primary
- 5 lessons per day, 25 per week; each lesson 30 minutes.
- Reporting time: 8:30 am. Lesson block: 9:00 am to 12:00 pm.
- Two health breaks (10 and 20 minutes). No double lessons.
Grade 1–3
- 6 lessons per day, 31 per week; each lesson 30 minutes.
- Reporting time: 8:00 am. Lessons: 8:20 am to 12:30 pm.
- Health breaks after every two lessons (first 10 min, second 30 min).
Grade 4–6
- 7 lessons per day, 35 per week; each lesson 35 minutes.
- Lessons run from 8:20 am to 2:35 pm. Balance morning and afternoon subjects.
- Non-formal programmes should be placed after the last lesson.
Grade 7–9 (Junior school)
- 8 lessons per day, 41 per week; each lesson 40 minutes.
- Lessons run 8:20 am to 3:20 pm. One double lesson allowed for practicals only.
- Health breaks: after every two lessons (10 min, 30 min) and a one-hour lunch.
Timetabling for special needs education and pre-vocational
Special needs timetables are more individualised. Foundation level typically has 4 lessons per day (20 per week) of 30 minutes each. Pre-vocational level runs 8 lessons per day (40 per week) of 40 minutes, with one double lesson allowed for practical skills.
How to compute CBE (step-by-step)
- Step 1: Sum weekly lessons per learning area across grades. Example — English: Grade 7 (5) + Grade 8 (5) + Grade 9 (5) = 15 lessons.
- Step 2: Divide total lessons for each subject by the teacher workload (27 lessons/week) to get teachers required per subject. Example: 15 ÷ 27 = 0.555.
- Step 3: Add required teachers across all subjects to get total teaching requirement.
- Step 4 (shortfall): Calculate shortfalls from administrative posts (principal 10 lessons, deputies 20, senior masters 20). Convert shortfall to teacher units by dividing by 27.
- Final CBE: Add teacher units from Step 3 and shortfall units. Round up to the next whole number.
Principals, deputies and senior staff workload
Workload benchmarks reduce teaching time for administrative roles: principal at least 10 lessons/week; deputy principals and senior masters at least 20 lessons/week. These reduced loads are used to compute shortfall and the additional teachers required to fill teaching time lost to administration.
CBE for stage-based pathway and special needs ratios
Stage-based CBE (foundation, intermediate, pre‑vocational) is determined by learner numbers and disability types. Typical teacher-to-learner ratios:
- Severe Autism, Cerebral Palsy, Deaf blindness, Multiple disabilities: 1:1–1:5 depending on severity.
- Intellectual disabilities (mild to moderate): 1:4 in many cases.
- Pre-vocational settings often use a 1:4 or similar ratio for practical skills.
Practical compliance tips for schools
- Form a timetabling committee with deputies, senior teachers and subject leads and meet each term to review the timetable.
- Display the approved timetable in administrative offices and notice boards. Provide every teacher with an extract for lesson delivery.
- Base lesson content and allocations on the approved curriculum designs — consult the CBC curriculum designs when plotting learning areas.
- Use available teaching resources and plans to align lessons. See the CBC lesson plans for ready-made sequences and activities.
- For subject-specific planning and senior school transition, review the Grade 10 curriculum designs when preparing junior learners for progression.
- Adjust start and end times only in extreme conditions, while keeping total contact hours unchanged.
Conclusion
Following the CBE timetabling rules ensures a balanced school day, consistent lesson coverage and a defensible teacher establishment. Apply the stepwise CBE calculation, follow lesson allocation rules per level, and use the recommended resources and templates to keep timetables learner‑centred and compliant.
