Should My Child Take the Optional ACT Science Section in 2026–2027?

With ACT Science now optional, families face a new decision: should a student take the extra section or concentrate on the core ACT?

There is no universal answer. The right choice depends on the student’s application plans, testing strengths, preparation time and the policies of the institutions or programmes they are considering.

What has changed?

ACT’s current test overview states that Science and Writing are optional and do not affect the Composite score. ACT also lists the optional Science section as 40 minutes, with 40 questions, including 34 scored questions.

Optional does not mean irrelevant. It means families should make a deliberate decision rather than register automatically.

Consider taking ACT Science when…

The section may be worthwhile if:

• a target institution, scholarship or programme requires or recommends it
• the student is applying in a science-related direction and wants an additional science-reasoning score
• practice results show Science is a relative strength
• the student can prepare without weakening English, Maths or Reading
• the extra test time is manageable

The first point matters most. Requirements can change, so check the official admissions pages for every realistic destination rather than relying on a general list or an old forum post.

Skipping may be sensible when…

Not taking Science may be reasonable if no target requires or values it, the student’s preparation time is limited, and the added section would create fatigue without strengthening the application.

It can also make sense when the core sections need urgent attention. A student should not neglect a major Maths or Reading weakness merely to add an optional score with no clear purpose.

Do not decide from school science grades alone

ACT Science is not simply a Biology, Chemistry and Physics recall test. It measures interpretation, analysis, evaluation and scientific reasoning through passages, graphs, tables and investigations.

A student with excellent classroom science grades can struggle with the pace. Another student who does not see themselves as a “science person” may perform well because they read evidence carefully.

Use a timed, current-format diagnostic before deciding.

Run a simple decision process

1. List realistic colleges, universities, scholarships and programmes.
2. Check their current official testing guidance.
3. Take one current ACT Science diagnostic under timed conditions.
4. Compare the score and fatigue cost with the student’s core-section priorities.
5. Estimate how much preparation would be needed.
6. Recheck policies before registration and application submission.

If the diagnostic is below target, first determine whether the problem is timing, graphs, experimental design or evidence evaluation. A low score does not automatically mean months of science content review.

Parents should frame this as a strategic choice, not a judgement of ability. The question is not “Is my child good enough for Science?” It is “Will this score serve a clear purpose, and can we prepare efficiently?”

Revisit the choice if plans change

A student’s college list, intended programme or practice profile may change during the year. Save the links and date of every policy you check, then review the decision before the relevant registration deadline. If Science is added, leave enough time for a current-format diagnostic and focused preparation. If it is dropped, redirect that time intentionally rather than allowing it to disappear.
