KNEC Releases Guidelines and October Deadlines for Inaugural Grade 10 SBA Written Tests

Term 3 SBA Checklist: What Principals Must Know About the New KNEC Grade 10 Written Tests

The educational landscape in Kenya has officially entered a transformative chapter. As the pioneer cohort of the Competency-Based Curriculum (CBC) navigates its transition into senior school, the Kenya National Examinations Council (KNEC) has taken a monumental step in solidifying the architecture of senior secondary evaluation.

In an official circular dated August 14, 2026, bearing reference number KNEC/GEN/TD/SE/G10 SBA/GUI/2026/02, KNEC Chief Executive Officer Dr. David Njengere released the comprehensive guidelines and operational schedules for the inaugural Grade 10 School-Based Assessment (SBA) written tests.

This release marks a critical milestone for educators, school administrators, parents, and learners alike. For the first time under the senior school tier, students are slated to sit for standardized written assessments that test higher-order cognitive application, theoretical depth, and analytical capacity.

Coming on the heels of the practicals and projects executed during the second term, these written tests complete the multifaceted evaluation framework designed to capture holistic learner development.

This comprehensive guide details the circular’s directives, the portal logistics, subject breakdowns, strict timelines, and the broader roadmap toward the eventual award of the Kenya Certificate of Basic Education (KCBE).

The Structural Framework of Senior School Assessment

The Competency-Based Curriculum was conceptualized to depart from rote memorization, shifting instead toward a dynamic, skills-oriented framework.

In senior school, this philosophy manifests through a carefully balanced tripartite assessment model.

Rather than relying on a single, high-stakes national examination at the end of a cycle, the system leverages formative and summative touchpoints to paint an accurate portrait of a learner’s academic journey.

The senior school evaluation framework is inherently multifaceted, integrating three core assessment modalities:

• Projects: Designed around real-world problem-solving scenarios, encouraging learners to apply classroom theories to community or industrial challenges.
• Practicals: Focused on evaluating hands-on technical skills, laboratory competencies, creative execution, and kinetic proficiency across varied specialized subjects.
• Written Tests: Aimed at assessing theoretical understanding, critical thinking, synthesis, and deep cognitive application across diverse learning areas.

The administration of these components follows a structured annual calendar. Projects and practical components are designated for execution during the second term, running between May and September each year.

For the pioneer Grade 10 cohort, these practicals and project-based evaluations were successfully administered in Term II, allowing learners to demonstrate their applied competencies.

Conversely, the final written assessments are slated for Term III. They represent the culmination of the academic year’s theoretical engagement, challenging students to articulate complex concepts through structured written responses.

Once administered, all final tasks, evaluations, and scores must be collated and uploaded into the national database by the designated deadlines, setting the stage for centralized reporting and longitudinal progress tracking.

Accessing the KNEC CBA Portal: Administrative Protocols

The administration of the 2026 Grade 10 SBA written tests relies heavily on digital efficiency through the KNEC Competency-Based Assessment (CBA) portal.

To ensure data integrity, security, and seamless deployment, KNEC has outlined strict protocols for school principals and subject teachers.

Portal Access and Authentication

Principals are required to access the assessment tools exclusively via the official CBA portal link: https://cba.knec.ac.ke.

Accessing the system requires institutional credentials, specifically the school’s registered username and password.

To safeguard the integrity of the examination materials, the portal employs a two-factor verification mechanism: a One-Time Password (OTP) is automatically dispatched to the principal’s officially registered mobile number upon login attempts.

Troubleshooting and Technical Support

Recognizing that digital platforms occasionally experience logistical hurdles, KNEC has provided clear guidelines for troubleshooting.

Schools encountering authentication failures or password retention issues are instructed to utilize the self-service ‘forgot password’ function embedded directly within the portal login interface to reset their credentials securely without unnecessary administrative delays.

Role of Principals and Subject Teachers

The operational chain of custody for the assessment tools places direct accountability on institutional leadership and academic staff:

Principals: Act as the primary custodians of the assessment process. They are responsible for downloading the assessment tools, ensuring secure storage, monitoring administration, overseeing scoring, and guaranteeing that all learner scores are successfully uploaded within the stipulated timeframe.

Furthermore, principals are mandated to meticulously archive all physical and digital records, student scripts, and evidence generated during the assessments for auditing and verification purposes.

Subject Teachers: Tasked with the direct administration of the assessment tools within their respective classrooms.

They manage the invigilation, execute objective scoring based on standardized rubrics provided by KNEC, and upload individual learner outcomes onto the portal.

Material Preparation and Digital Integration

A critical operational instruction highlighted in the circular addresses the nature of the test materials. Assessment tools containing colour images must be printed strictly in full colour to preserve the contextual accuracy of diagrams, charts, and illustrations.

Alternatively, schools possessing adequate digital infrastructure may load the materials directly onto digital learning devices available within the institution, aligning with the government’s push toward digital literacy and green-smart schools.

Comprehensive Subject Schedule and Timelines

Preparation is paramount for the smooth execution of the Term III evaluations. The 2026 Grade 10 SBA written tests span across three broad learning clusters: STEM (Science, Technology, Engineering, and Mathematics), Social Sciences, and Arts & Sports.

According to the official circular signed by Dr. David Njengere, all assessment tools across these diverse learning areas will be simultaneously availed on the portal, and schools must complete the entire cycle of administration, scoring, and score uploading within a tightly regulated window.

Master Schedule for Grade 10 SBA Written Tests

Learning Cluster	Specific Subjects Included	Date Tools to be Accessed	Last Date to Upload Scores

Arts & Sports	• Sports & Recreation • Music and Dance	5th October 2026	23rd October 2026

Detailed Step-by-Step Guidance for Schools

To eliminate ambiguity during the administration window, KNEC has made a comprehensive user manual available directly on the CBA portal homepage. This manual provides an exhaustive, step-by-step walkthrough detailing:

1. Tool Extraction: Protocols for downloading encrypted assessment files safely.

2. Administration Instructions: Specific timing, environmental setups, and special accommodation guidelines for learners with diverse needs.

3. Scoring Guides: Standardized rubric interpretations to ensure uniformity in grading across diverse educational contexts nationwide—from well-equipped national schools to rural day secondary institutions.

4. Data Entry Protocols: Navigating the score-upload interface to prevent data entry errors, missing indices, or mismatched learner registration details.

School heads and academic departments are strongly advised to download and review this manual immediately upon its release to brief their teaching staff well before the October 5 download date.

Reporting Outcomes: The Path to the Kenya Certificate of Basic Education (KCBE)

The ultimate institutional goal of these rigorous assessment efforts is the eventual issuance of the Kenya Certificate of Basic Education (KCBE) upon the completion of the senior secondary cycle in Grade 12.

The reporting and grading structure for the KCBE represents a radical, progressive departure from traditional, high-stakes, exam-only systems.

Instead of penalizing a student for a single bad day in an end-of-cycle examination room, the KCBE grading architecture balances formative assessments conducted continuously throughout senior school with a final summative evaluation.

The Weighted Grade Contribution Model

A learner’s final subject grade for the KCBE is calculated using a cumulative weighted formula distributed across the three senior secondary grades:

• Grade 10 School-Based Assessments (SBA): Contributes 15% to the final grade, capturing foundational competencies, project work, practical skills, and the newly introduced written tests.

• Grade 11 School-Based Assessments (SBA): Contributes 15% to the final grade, measuring advanced formative development, continuous growth, and deepening specialization.

• Grade 12 Summative Assessment: Contributes 70% to the final grade, serving as the capstone national examination administered at the end of the senior school cycle.

This balanced approach ensures that a student’s daily effort, creativity, consistency, and practical mastery—captured diligently through the SBAs in Grades 10 and 11—constitute a robust 30% of their final certification grade.

The remaining 70% is derived from the Grade 12 summative assessment, creating a holistic evaluation ecosystem that rewards long-term academic engagement rather than last-minute cramming.

Looking Ahead: The 2027 Piloting and Long-Term Vision

The release of these guidelines is not merely an isolated administrative event; it is part of a meticulously mapped macro-strategy.

KNEC has already announced that the piloting of the Senior School summative assessment (KCBE) is officially scheduled for 2027.

This pilot will take place when the pioneer cohort currently undertaking these Grade 10 assessments progresses seamlessly into Grade 11.

This forward-looking, iterative approach underscores KNEC’s institutional commitment to refining the assessment process based on empirical, real-world data, institutional feedback, and systemic adjustments.

By stress-testing the mechanics of score uploads, rubric applications, and portal capacities incrementally, the council ensures that the evaluation ecosystem matures alongside the learners.

By the time this pioneer cohort reaches the finish line in Grade 12, the entire educational ecosystem—comprising national administrative systems, classroom teachers, school principals, and the learners themselves—will be deeply well-versed in the demands, nuances, and expectations of the Competency-Based Curriculum.

This thorough preparation guarantees a friction-free transition for graduates, equipping them with verified competencies to either excel in higher education institutions or transition directly and competitively into a dynamic, modern labor market.

Institutional Imperatives: Action Points for Schools

As the calendar ticks toward October 2026, school administrators must immediately operationalize the directives contained in the KNEC circular.

The tight turnaround between the download date (October 5, 2026) and the final upload deadline (October 23, 2026) leaves no room for administrative inertia.

Key action items for school leadership include:

Portal Audit: Verify active school credentials, test login stability on the CBA portal, and ensure the principal’s mobile phone number is current for receiving OTP prompts.

Staff Capacity Building: Conduct internal departmental workshops utilizing the KNEC user manual to familiarize all subject teachers with the specific scoring rubrics and administration guidelines.

Resource Allocation: Ensure printers, high-yield colour ink cartridges, and secure digital devices are fully serviced and ready for the reproduction of image-heavy assessment tools.

Data Integrity Compliance: Establish a secure physical and digital archiving system to store learner assessment booklets, practical evidence, and score sheets as mandated by KNEC directive clause 8.0.

Through proactive planning, strict adherence to timelines, and unwavering commitment to formative educational principles, schools will play a pivotal role in cementing the success of Kenya’s educational transformation.

The 2026 Grade 10 SBAs are more than tests; they are stepping stones toward a globally competitive, competence-driven future for Kenyan youth.
