Understanding cbc test details is crucial for Kenyan parents, teachers, and learners navigating the combination of continuous School-Based Assessments (SBAs) and national examinations. Formulated by KNEC and KICD, the evaluation structure assigns significant weight to ongoing classroom projects and portfolios alongside summative tests like KPSEA in Grade 6 and KJSEA in Grade 9.

Breakdown of School-Based Assessment Components

School-Based Assessments (SBAs) are conducted by classroom teachers from Grade 4 through Grade 6 and continuing into Junior Secondary. SBAs account for 60% of total cumulative marks in national placement calculations.
SBAs consist of written assignments, practical science experiments, oral presentations, artistic projects, and community service tasks. Teachers evaluate performance using standardized KNEC rubrics, uploading student scores to the official KNEC assessment portal.

Summative National Assessments: KPSEA and KJSEA Specifications

Summative assessments provide national standardization at key educational transition milestones:
  • KPSEA (Grade 6): Administered at the end of Upper Primary, contributing 40% toward cumulative score profiling. Papers cover Mathematics, English, Kiswahili, Elementary Science & Technology, Social Studies, and Religious Education.

  • KJSEA (Grade 9): Administered at the end of Junior Secondary to evaluate learning outcomes and guide student placement into Senior Secondary pathways (STEM, Social Sciences, Arts & Sports).
  • Grading Criteria and Performance Levels in CBC Testing

    CBC tests move away from traditional letter grades and rankings, utilizing a 4-level rubric scale:
  • Level 4: Exceeding Expectations (EE)

  • Level 3: Meeting Expectations (ME)

  • Level 2: Approaching Expectations (AE)

  • Level 1: Below Expectations (BE)
  • Detailed descriptors accompany these levels, highlighting specific competencies achieved and areas requiring remedial attention.
