What is School-Based Assessment in CBC — and does it count for KPSEA / KJSEA?

Last updated: 6 September 2026

What is SBA in CBC? How does it affect KPSEA / KJSEA? Can an app do it for us? School-Based Assessment is the KNEC-tooled, teacher-administered continuous assessment that starts from Grade 4 and sits alongside classroom tests and national papers (KPSEA at Grade 6, KJSEA at Grade 9). Kenyan education reporting commonly cites upper-primary mixes around 60% SBA + 40% national KPSEA, and a senior-school placement composite of about KPSEA 20% + Grades 7–8 SBA 20% + KJSEA 60% — always verify those shares against current KNEC/MoE guidance. Parents should get the Assessment Number and ask the school what is uploaded; teachers own the evidence and the portal. A CBC tutor like Kitabu can help a child practise and show parents progress — it does not grade SBA or submit scores to KNEC.

The WhatsApp question, in one paragraph

Someone drops a screenshot: “SBA is 60%.” Five minutes later another parent replies: “No — for KJSEA it is 20%.” A third person says KPSEA is monitoring tu. The class teacher is marking rubrics after school and does not have bandwidth to re-explain the CBA portal in a voice note. This page is the shared vocabulary you can forward — parents and walimu in one sitting-room/staffroom read — then a checklist for the next school meeting, then an honest boundary for any revision app. Si lazima you fight the percentages in the group chat; verify them against the school and current KNEC/MoE notices, and keep home practice separate from portal truth.

What SBA is (plain English)

CBC (Competency Based Curriculum, designed under KICD) is the syllabus and learning design. CBA (Competency Based Assessment, led by KNEC) is how evidence of what a learner knows and can do is gathered. Parents often say “CBC” for both; if the naming still confuses you, see CBC vs CBE explained.

KNEC’s public CBA framing — widely reprinted in Kenyan education explainers — usually names three assessment types. Keep the labels clean:

1. Classroom assessment — continuous. The teacher develops the tools. It runs across basic education. Think ordinary quizzes, oral checks, short tasks the school designs for learning, not for a national upload.
2. School-based assessment (SBA) — from Grade 4 to Grade 12. KNEC develops and uploads the tools; the teacher downloads them, administers the tasks, scores with the given rubrics or guidance, and uploads results through the school’s CBA process (commonly discussed around cba.knec.ac.ke).
3. Summative / national assessment — at Grades 6, 9, and 12 (KPSEA, KJSEA, and the end-of-senior-school framing). These are the big national sittings parents already recognise by name.

Tools families hear about include projects, practicals, written tasks, portfolios, observation, and oral work. Exact menus shift by learning area and circular — ask the school for this term’s list rather than treating a blog post as the syllabus.

One line that cuts through the panic: SBA is continuous evidence the school gathers and uploads, not a surprise Saturday paper. Grades 1–3 still have serious classroom assessment; formal SBA language in KNEC framing typically starts at Grade 4. Kitabu itself covers Grades 1–12 for home revision — early grades get practice and visibility, not invented SBA percentage talk.

How SBA feeds KPSEA / KJSEA / Grade 10 placement (careful math)

Important: the percentages below are what Kenyan education reporting commonly cites (Education News Hub, Star / EduPoa-style explainers, Grade 10 placement roundups). Treat them as widely reported, not as a law we invented. Always verify against the latest KNEC or MoE notice for your child’s cohort before you argue from a screenshot.

Two packages parents confuse

These are different packages. That is why the WhatsApp fight never ends: one person is talking about the upper-primary mix; another is talking about the Grade 10 composite. Both numbers can appear in reputable explainers without one cancelling the other.

KPSEA’s 20% slice in the senior composite already carries earlier work — including the upper-primary SBA story that fed Grade 6. “KPSEA is just monitoring” is incomplete; we unpack that calmly in KPSEA isn’t “just monitoring”. For Grade 9 timing and slip language, keep KJSEA Grade 9 parents’ guide and KJSEA E before you panic beside this page.

Conflict to flag, not invent away: some outlets simplify “KJSEA overall” as 20% SBA + 80% national. Grade 10 placement explainers more often use the clean 20 / 20 / 60 composite (KPSEA + SBA G7–8 + KJSEA). We are not inventing a third reconciliation. Prefer dated primary sources, ask the school which frame they brief parents with, and verify rather than treat a WhatsApp graphic as policy.

We also do not invent pathway cut-scores. When slips and placement talks begin, the school’s briefing and official channels win.

Parent checklist: what to ask the school

Print this, screenshot it, or take it to the next meeting. Quotable on purpose.

1. What is my child’s Assessment Number (commonly linked to Grade 3 registration in parent guides) and how do I view details on cba.knec.ac.ke?
2. Which learning areas have SBA scores uploaded this term — and which are still missing?
3. For Grade 6 / Grade 9 candidates: has the school completed KNEC’s latest verification exercise for SBA uploads?
4. Who is the teacher of record for each learning area’s SBA (class teacher vs subject teacher)?
5. How are projects / practicals scheduled so we can support materials without doing the work for the child?
6. When will we see school-level feedback, not only a portal summary?
7. If we transfer schools mid-cycle, how will SBA records move (Sub-County / CBA portal process — ask for the school’s high-level steps)?
8. What does the school expect parents not to do (for example, completing projects for the learner)?
9. How should home revision relate to SBA — practise skills vs copying portal tasks?
10. Who do I contact if portal details look wrong (school first, not a homework app)?

Kitabu cannot answer portal disputes. The school and KNEC systems own the learner’s assessment record. If home practice starts to become “doing the project for them,” read help with CBC homework before the next deadline.

For teachers: SBA is real work (honesty)

Download tools → administer → mark with rubrics → upload → headteacher verify or lock. That chain is labour on top of teaching. Parents feel continuous assessment as a rumour; you feel it as evenings and weekends.

Parent panic often arrives as a WhatsApp voice note at 9 p.m. A shared plain-English page reduces the number of times you re-explain Assessment Numbers, verification windows, and why “the app will upload for us” is not a thing. Point guardians here plus the school’s circular; keep verification ahead of whatever deadline the current KNEC notice names for your cohort.

Apps that claim to “handle SBA,” mark school projects for the portal, or submit scores to KNEC create compliance risk and trust damage. The portal is school work. Teacher judgment is teacher work. Anything that blurs that line puts the school, not the vendor, in the difficult seat when uploads are audited.

Kitabu’s honest lane is after-school revision and parent visibility — diagnostic practice, step-by-step explanations, past papers — so families stop treating every evening as a prosecution. Teacher judgment stays with the teacher. School pilots, where they exist, are for learning support, not for replacing CBA uploads. See for teachers and school pilots and AI learning.

How Kitabu helps revision without replacing SBA

Only after the system is clear: Kitabu is a CBC-aligned AI tutor for Kenyan learners in Grades 1–12, in English and Kiswahili. Built by Jambo AI Studio in Nairobi. It finds a starting point with a short diagnostic, then walks the child through guided practice they do themselves — the same skill strands SBA and national papers care about, without touching the school’s evidence file.

From the KSh 100/month plan (list KSh 250), families get KPSEA, KJSEA, and KCSE past papers in the same habit as ordinary revision. Termly is KSh 250 (list KSh 500). Premium Package is KSh 999/term for priority parent progress insights. 1-month free trial for all students; pay later with M-Pesa. Android is live on the Play Store; iOS and web are coming. Parents see a dashboard and a Friday WhatsApp progress note so umesoma? is not the only conversation.

Explicit boundary: Kitabu does not grade SBA, does not mark school projects for the portal, and does not upload or submit scores to KNEC or cba.knec.ac.ke. Revision after red ink is still your family’s job — method in past papers after the red ink. More on what the product is (and is not) in What is Kitabu AI and current pricing.

If Grade 6, Grade 9, and Form 4 share one roof, separate the jobs — three exam classes under one roof. If you need a calm Grade 6 plan, keep the KPSEA Grade 6 revision guide next to this explainer.

A simple house + staffroom rule this term

• School owns SBA evidence, rubrics, moderation, and portal truth.
• Home owns practice, sleep, materials support, and the discipline not to ghostwrite projects.
• Apps own guided revision and parent visibility — not placement decisions, not Assessment Number disputes, not KNEC uploads.

When someone in the group chat asks whether a tutor “does SBA,” the answer is the rule above. Practice skills at home. Leave the record at school.

How to start this week

Parents: find the Assessment Number → open the CBA parent view on cba.knec.ac.ke → ask the school which learning areas are still outstanding → pick one weak strand → run a free Kitabu diagnostic and practise that strand yourself (child does the work). Use is my child really revising if screen time is the real fight.

Teachers: share this page with the class WhatsApp alongside the school circular; keep verification windows on your calendar; keep any revision tool in the “practice only” lane.

No hard sell. Clarify the system first. Then choose a practice habit that does not pretend to be the portal.

Common questions

What is the difference between CBA and SBA?

CBA is the wider Competency Based Assessment system. SBA is one type inside it: the KNEC-tooled, school-administered continuous assessment from Grade 4 to Grade 12. Classroom assessment and national summative papers (KPSEA / KJSEA / Grade 12) sit beside it, not inside the same label.

Does SBA count toward senior school placement?

Widely reported Grade 10 placement explainers treat SBA across Grades 7–8 as about 20% of the composite, alongside KPSEA (~20%) and KJSEA (~60%). Upper primary has its own commonly reported ~60% SBA / ~40% KPSEA package. Verify both frames against current KNEC/MoE guidance for your cohort.

Can I see my child’s SBA scores online?

Parent guides commonly describe viewing learner details on cba.knec.ac.ke with the Assessment Number and grade. Ask the school for the exact steps they brief parents on this term — portal screens change, and the school remains your first stop if something looks wrong.

Is KPSEA “just monitoring”?

No — not if you mean “zero weight.” Public explainers give KPSEA a real share of later placement math, and Grade 6 already sits on years of upper-primary evidence. Culture cooled the old KCPE ranking theatre; that is not the same as “skip revision.” Details: KPSEA isn’t just monitoring.

Will an AI tutor upload SBA for our school?

No honest one should claim that. Kitabu does not grade SBA and does not submit scores to KNEC. Uploads, verification, and teacher judgment stay with the school.

How much does Kitabu cost this season?

Monthly KSh 100 (list 250). Termly KSh 250 (list 500). Premium Package KSh 999/term. 1-month free trial. KPSEA, KJSEA, and KCSE past papers from the KSh 100 plan. Pay with M-Pesa when ready — see pricing.
