Grade 10 STEM Pathway: What You Actually Study (Math Isn't Even Compulsory)

Once a Grade 9 learner is placed into the STEM pathway, the question most parents ask next is simple: what will they actually be studying? The pathway name tells you the direction, not the timetable. Here is the real subject structure, including one detail that surprises most families.

This guide is written for parents of the 2026 Grade 10 cohort, the first CBC senior school learners, and for families whose Grade 9 child is sitting KJSEA from 26 to 30 October 2026 and will join senior school in January 2027. It explains the compulsory core, the three groups of STEM electives, what each kind of subject feels like in practice, and the questions worth asking a school before your child settles into a combination.

The Compulsory Core, and a Genuine Surprise

Every Senior School learner, regardless of pathway, takes 4 core subjects: English, Kiswahili (or Kenyan Sign Language for deaf learners), Mathematics and Community Service Learning, plus 3 pathway subjects, 7 in total. STEM learners take Core Mathematics, the more demanding of the two Mathematics courses; learners in the other pathways take Essential Mathematics.

There is one newer development worth knowing about. KICD publishes two Grade 11 Mathematics curriculum designs, Core Mathematics and Essential Mathematics, so ask the school which one, if either, your child will take. In plain terms, the old idea of one single Mathematics paper that everybody sits in exactly the same form has gone, and the real question for a STEM family is which Mathematics their child is taking. For most STEM routes, especially pure sciences and engineering-type technical subjects, the more demanding Core version is the one to ask about. Check the school's arrangement directly, because this is exactly the kind of detail that is easy to assume and expensive to discover late.

What STEM Actually Offers on Top of the Core

Beyond the 4 compulsory subjects, STEM learners choose their remaining subjects from a genuinely wide elective pool, wider than the "STEM" label alone suggests:

• Pure Sciences: Mathematics, Biology, Chemistry, Physics, General Science
• Applied Sciences: Agriculture, Computer Science, Home Science, Drawing and Design
• Technical and Technology subjects: Aviation Technology, Building and Construction, Electrical Technology, Metal Technology, Power Mechanics, Wood Technology, Media Technology, Marine and Fisheries Technology

This is worth sitting with for a moment: STEM does not mean every learner does Physics, Chemistry and Biology. A learner drawn to Building and Construction or Electrical Technology is just as much a STEM learner as one heading toward pure sciences, and the two subject combinations lead to very different further-study and career routes. "My child is in STEM" tells you almost nothing on its own, the actual elective choices are what matter.

The Three STEM Groups Side by Side

The table below describes each group in general terms. It is a guide to the kind of work involved, not an official combination list, so use it to start a conversation with the school rather than to decide on your own.

What Each Group Asks of a Learner

Pure Sciences

Pure sciences reward a learner who is comfortable with abstract ideas and who can keep going when a problem does not work out the first time. Practicals matter, but so does writing a clear explanation of what was observed and why. A learner who found Integrated Science and Mathematics manageable at Junior Secondary, and who is willing to practise regularly, usually copes well here.

Applied Sciences

Applied sciences take scientific ideas and put them to work. Computer Science involves logical problem solving, Agriculture links biology and chemistry to land and food, Home Science covers nutrition and household management, and Drawing and Design builds technical drawing skill. Many learners who felt lost in pure theory come alive when the purpose of the lesson is obvious.

Technical and Technology Subjects

These subjects are hands-on and project based. Learners work with tools, materials and safety procedures, and they still need measurement, calculation and accurate drawing. They suit practical learners, but they are not an easy option: a well-made project needs planning, patience and precision. They also depend heavily on what the school has in its workshops, which is why the questions below matter.

Why the Elective Choice Matters More Than the Pathway Label

Because STEM spans everything from theoretical physics to hands-on technical trades, the real decision point isn't "should my child do STEM," it's which specific electives within STEM fit their strengths and goals. A learner strong in the practical, applied sciences but weaker in abstract mathematics may be far better served by a Technical/Technology-heavy combination than by forcing Physics and Chemistry because "STEM sounds academic." Talk to the school directly about which specific subjects are being offered and which combinations are realistic given the learner's Grade 9 performance, not just which pathway they were placed into.

Our guide to senior school subject combinations compares how STEM sits next to the other two pathways, which helps if your child is borderline between two.

Why Grade 10 Work Counts From the Start

Under KCBE, the final senior school result is built from three parts: Grade 10 school-based assessment (SBA) counts for 15%, Grade 11 SBA for another 15%, and the Grade 12 summative assessment for 70%. That means the work your child does in their STEM electives during Grade 10 already feeds into the final grade. A learner who drifts through the first year expecting to catch up later gives away marks they cannot recover. For how schools record those scores, see our guide to the Grade 10 SBA schedule.

Questions to Ask the School

1. Which STEM electives does the school actually offer this year, and which are full?
2. Which version of Mathematics will my child take, Core or Essential, and who decides?
3. For technical subjects, is there a working workshop and a trained teacher for each one?
4. How are SBA tasks set and recorded in each elective, and how will we see the scores?
5. If the combination turns out to be wrong for my child, is there a window to change?

A Note on the Source of This Information

We're flagging honestly that the exact final elective list can vary slightly in how different sources describe it, since we were not able to access a primary KICD curriculum-design document directly while researching this piece, only consistent reporting across several credible Kenyan outlets. Confirm your specific school's actual subject offering list directly with them, since not every school will offer every technical/technology option listed above.

Frequently asked questions

Does every STEM learner study Physics, Chemistry and Biology?

No. STEM includes pure sciences, applied sciences and technical subjects. A learner taking Electrical Technology and Computer Science is still in STEM. The specific electives the school confirms are what your child will actually study.

Is Mathematics compulsory in STEM?

Yes. Mathematics is one of the four core subjects for every Senior School learner, and STEM learners take Core Mathematics, which most pure science and engineering routes depend on.

Can a learner who struggled with Mathematics still do well in STEM?

Often, yes, especially in applied or technical subjects. Be honest with the school about Grade 9 performance so they can suggest a realistic combination, and plan steady Mathematics practice from the first term.

How can my child prepare before January 2027?

Read ahead in the subjects they are likely to take and keep Mathematics ticking over in the December holiday. Our December holiday plan for parents sets out a simple routine.
