KJSEA 2026 for Teachers: The Final Week, Rehearsal and KNEC Rules

By the week of 19 October, the teaching is done. School-based assessment for Grades 7 and 8 is recorded, the projects for Creative Arts and Sports, Pre-Technical Studies and Agriculture were completed between May and July, and most schools have run at least one mock. What remains for a Grade 9 teacher is a short, high-value week: closing the last gaps, teaching candidates how the assessment room works, running a calm rehearsal, and making sure nobody loses marks or results to a rule they did not know.

KNEC is direct about the teacher's part in this. Section 3.1 of its 2026 KJSEA instructions asks teachers to make sure candidates read the instructions and guidelines carefully and follow them, and to make candidates aware of the penalties for examination irregularities. This guide turns that duty into a practical plan for the final week before KJSEA: what to teach each day, a lesson built on the KNEC instructions, a checklist for the rehearsal, and the rules that apply in the assessment week itself. It also points you to a resource many schools have not yet used: KNEC's own 2025 KJSEA feedback reports.

Information current as of Term 3, October 2026.

The final week before KJSEA: what teachers should prioritise

The single best guide to the last lessons is evidence of where candidates lose marks. You have two sources. The first is your own mock scripts. The second is national. According to Kenyans.co.ke, on 7 September 2026 KNEC made available its 2025 KJSEA feedback reports in three volumes (Languages, Sciences, Pre-Technical Studies and Mathematics; Humanities; and Creative Arts and Sports), together with the 2025 KJSEA assessment papers and marking schemes, through the KNEC Bookshop in Nairobi. The reports are intended, in KNEC's framing as reported, to help teachers and schools identify areas of strength and weakness. If your school bought them, put the relevant volume in front of each subject teacher this week. If not, the national subject results below still tell you where to look.

Source: Ministry of Education 2025 KJSEA results, 1,130,459 candidates, as reported by Citizen Digital and The Standard on 11 December 2025. English, Pre-Technical Studies and IRE were not given a single overall figure in the reports we found.

Target the learners near a boundary

KJSEA reports each learning area on eight achievement levels. According to KNEC's explanation reported by The Star in December 2025, the boundaries are as shown below. The practical lesson for a teacher with one week left is to look at each learner's latest mock percentage and ask how close it is to the next boundary. A learner on 38 percent sits in AE1, three percentage points below the ME2 floor of 41; a learner on 55 percent is three points below ME1. Those learners gain the most from a week of technique work.

The "mock scores to target" column is our suggestion, not a KNEC rule: it simply marks learners within about five percentage points of the next level. It works best when a mock was marked strictly against a scheme. For how to run and mark a mock well, see our teacher's guide to running KJSEA mock exams.

A day-by-day plan for the last teaching week

The plan below is for a class teacher coordinating subject teachers. It mirrors the order of the real assessment, so each subject gets its last technique lesson a few days before its paper.

Keep each subject lesson to technique and correction, not new content. A lesson that ends with five marked questions and a correction written beside each lost mark is worth more this week than a lesson of notes. Parents will ask what to do at home; our KJSEA 3-week revision timetable is written for them and fits alongside this plan.

The KNEC instructions lesson: teaching the rules candidates must follow

KNEC's instructions to candidates are short, specific and easy to teach in one 40-minute lesson. Read each one aloud, then show what it looks like in practice. The table pairs the instruction with the classroom demonstration.

End the lesson with the penalties, because KNEC asks teachers to cover them. The KNEC instructions state that a candidate who commits an irregularity in any paper will have the results for the whole subject cancelled, and that widespread irregularities at a centre can lead to cancellation of results for the whole centre. They also summarise offences under the KNEC Act No. 29 of 2012, sections 27 to 40: for example, revealing assessment material to an unauthorised person carries a penalty of up to ten years' imprisonment, a fine of up to two million shillings, or both, under section 27. Learners should hear this calmly and clearly, along with a reminder that so-called leaked papers sold online are scams; our guide to KJSEA leaked-paper scams is a useful handout for parents.

Running the rehearsal on Friday 23 October

KNEC's timetable lists Friday 23 October as rehearsal day. Use it to remove every surprise from Monday morning. A checklist for the class teacher:

1. Room and seat. Every candidate knows the room and seat for Monday.
2. Names and numbers. Candidates check that their name and assessment number are spelled correctly wherever they appear, so any error can be raised with the head teacher before Monday.
3. Timings. Seating times for each day written on the board and copied: 8.15 a.m. every morning, and the second and third session times.
4. Equipment. Pens, pencils, eraser, sharpener, ruler, geometrical set, calculator. Note anyone without, and solve it today.
5. Special needs. Learners using Braille or with hearing impairment have different durations on the KNEC timetable. Confirm that they and their parents know the times.
6. Lunch on Thursday and Friday. Both days have an afternoon paper at 2.00 p.m. Tell parents what the lunch arrangement is.
7. Phones. Repeat the rule. Tell candidates to leave phones at home.

If you are serving in the assessment week

Many junior school teachers serve as invigilators, supervisors or centre managers during national assessments. If you are one of them, KNEC's guidelines in section 3.4 include these points:

• A supervisor is deployed for every 200 candidates, and every assessment room of up to 20 candidates must have an invigilator.
• Only authorised persons are allowed in the centre while the assessment is going on.
• Candidates must be issued with personalised question papers bearing their names and random numbers, among other features KNEC communicates during the assessment.
• Supervisors must check that candidates have signed their answer scripts and the script control form before collecting them, and count the scripts against the candidates present.
• Absent candidates are marked AB in red against their assessment number on the script control form and on the return cover page.
• The KJSEA seating plan and script control forms must not be stamped by the centre manager, and must not carry school details. Every return polybag must have a script control form.
• Scripts are spread evenly across the return envelopes and cover pages provided, not over-stuffed into one.

Read the full KNEC instructions document and any briefing your sub-county gives you. Where a briefing gives a more detailed instruction, follow it.

Common mistakes in the last week

• Teaching new content. Learners cannot absorb a new sub-strand in four days and sit twelve papers the week after.
• Skipping the instructions lesson. KNEC asks teachers to cover it, and it protects marks and results.
• Treating the rehearsal as a free day. It is the last chance to fix a misspelt name, a missing calculator or a wrong seating time.
• Only coaching the strongest learners. Learners near a boundary at every level gain from a week of technique work.
• Not telling parents the rules. A short written note on timings, lunch and phones prevents most morning problems.

Resources for teachers this week

For timed class practice, the KJSEA Complete Revision Course covers all nine learning areas with predictive papers and separate answer booklets that teachers can print for the class and keep for marking. These are original papers by CBC Edu Kenya, not KNEC papers. Lesson plans, schemes and notes for Grade 9 are on the Grade 9 hub, and the free KJSEA Mini-Mock is a quick class check across every learning area. Our explainer on how the KJSEA weighting works is useful when parents ask how the final result is built.

Frequently asked questions

What does KNEC expect teachers to do before KJSEA?

Section 3.1 of KNEC's 2026 KJSEA instructions asks teachers to make sure candidates read the instructions and guidelines carefully, follow them, and know the penalties for examination irregularities.

When is the KJSEA 2026 rehearsal?

Friday 23 October 2026, according to KNEC's revised timetable. The written papers run from Monday 26 to Friday 30 October.

Where can teachers get the 2025 KJSEA papers and feedback reports?

According to Kenyans.co.ke, KNEC made the 2025 KJSEA feedback reports, assessment papers and marking schemes available through the KNEC Bookshop in Nairobi from 7 September 2026.

How many candidates can one invigilator oversee?

KNEC's guidelines say every assessment room with a maximum of 20 candidates must have an invigilator, and a supervisor is deployed for every 200 candidates.

What happens if a candidate is caught with a phone?

KNEC's instructions say a candidate found with a cell phone or any other electronic communication device will have results cancelled.

Should Grade 9 learners still have lessons during exam week?

Follow your school and sub-county arrangements. In practice, learners need short, quiet time between and after papers, not new lessons.

Conclusion

The final week before KJSEA is the teacher's last chance to turn what learners know into marks on paper. Use the 2025 KJSEA feedback reports or your own mock scripts to pick the last lessons, focus on learners near an achievement-level boundary, teach the KNEC instructions as a proper lesson as section 3.1 asks, and run Friday's rehearsal as a full check of names, seats, timings and equipment. If you serve in the assessment week, follow KNEC's guidelines on personalised papers, script control and absentees closely. A calm, prepared class on Monday 26 October is the best result of this week. For printable timed papers with separate answers, the KJSEA Complete Revision Course covers every learning area.
