The Kenya Junior School Education Assessment (KJSEA) 2025 is a key component of the Competency-Based Education (CBE) curriculum, determining how Grade 9 learners transition to Senior School. With the KNEC portal now open for registration, schools, teachers, and parents must ensure all eligible students are registered before the March 28, 2025, deadline.

This guide explains the registration process, exam structure, transition criteria, and the role of teachers in preparing students for KJSEA 2025.
1. KJSEA 2025 Registration Details
The Kenya National Examinations Council (KNEC) has directed all schools to complete KJSEA registration through the official KNEC portal login (www.knec.ac.ke). Schools must upload student data, including names and assessment records, before the deadline to avoid last-minute issues.
How to Register for KJSEA 2025
- Log in to the KNEC portal – Schools must use the JSS KNEC portal for official registration.
- Enter learner details – This includes the student’s name, school code, and previous KPSEA results.
- Confirm details and submit – Any errors in registration can be corrected via the KNEC CP2 portal before the deadline.
- Print the registration report – Schools should retain a copy for record-keeping.
Parents and teachers can track the registration status using the KNEC CBA portal login and should ensure learners are correctly enrolled to sit for the KJSEA exams in November 2025.
2. KJSEA 2025 Exam Structure
The KJSEA 2025 assessment model is designed to evaluate learners holistically, ensuring a smooth transition to Senior School. The final score is determined using a 60:40 ratio, comprising:
- 20% from KPSEA – This includes results from the 2022 KPSEA exams taken in Grade 6.
- 20% from School-Based Assessments (SBA) – Learners’ performance in Grades 7 and 8 contributes to the final score.
- 60% from KJSEA exams – The summative assessment in Grade 9 determines placement in Senior School.
Key Examination Components
- The KJSEA 2025 timetable will be released via the KNEC CBA portal to guide schools on exam dates.
- Sample exam papers will be made available through the KJSEA sample papers section on the KNEC website.
- Exams will assess practical, theoretical, and competency-based skills, aligning with the Competency-Based Education (CBE) curriculum.
Learners should prepare by using KJSEA sample papers and reviewing past assessments through the KPSEA portal and KPSEA 2024 exam papers PDF.
3. Key Differences Between KJSEA and KCSE

Unlike the Kenya Certificate of Secondary Education (KCSE), which determines university placement, KJSEA 2025 is designed for Senior School placement under the CBE curriculum.
Comparison of KJSEA and KCSE
Aspect | KJSEA 2025 | KCSE |
---|---|---|
Purpose | Senior School placement | University/college placement |
Assessment Structure | 60% KJSEA, 40% SBA & KPSEA | 100% national exams |
Subjects Tested | STEM, Social Sciences, Arts & Sports | Science, Arts, Humanities |
Results Access | KNEC portal, JSS KNEC portal | KNEC website (knec.ac.ke/kcse-results) |
Learners and teachers should use the KNEC examiners portal login to track performance and prepare accordingly.
4. Senior School Transition and Placement

After completing KJSEA 2025, learners will be placed into different Senior School pathways based on their scores and interests. Placement will be determined by:
- Performance in KJSEA exams – The final KJSEA score influences which school and pathway a learner is placed in.
- School-Based Assessments (SBA) results – Past performance in Grades 7 and 8 will contribute to placement.
- Learner preference and talents – Students can indicate interest in one of the three Senior School pathways:
- Arts & Sports Science
- Social Sciences
- Science, Technology, Engineering & Mathematics (STEM)
How to Find a Senior School
Parents can use Google searches like “JSS near me” or visit the KPSEA portal to find Senior Schools offering specific pathways. Schools with strong STEM or Arts programs will be listed based on KJSEA results and learner preferences.
5. How JSS Teachers Can Prepare for KJSEA 2025

JSS teachers play a crucial role in ensuring learners are well-prepared for KJSEA exams. To effectively support students, teachers should:
1. Use KNEC Resources
- Access KPSEA 2024 exam papers PDF to analyze past assessment formats.
- Log in to the KNEC CBA portal for updated curriculum materials.
- Download KJSEA sample papers for practice tests.
2. Monitor Student Progress
- Keep track of SBA scores and update records on the KPSEA attendance register.
- Use the KNEC CP2 portal to verify student registration.
3. Follow the KJSEA 2025 Timetable
- Ensure all learners sit for mock exams before the official KJSEA exams in November.
- Guide students in understanding KPSEA meaning and the importance of KJSEA results for Senior School placement.
Teachers can also use the KNEC CBA portal login and KNEC examiners portal to stay updated on assessment guidelines.
Conclusion
The KJSEA 2025 exams represent a major step in the Competency-Based Education (CBE) curriculum, shaping learners’ futures in Senior School. As the KNEC portal remains open for registration, parents, teachers, and students must engage with KNEC platforms like the JSS KNEC portal, KPSEA portal, and KJSEA sample papers to ensure full preparation.
