Sitting it as an English learner

Compiled by the Sitonce editorial team from the PSI Candidate Information Bulletin, NASCLA's own published material and the federal standards named belowUpdated 2 min readFacts verified 4 September 2026
The short answer

The examination is in English and the reading load is substantial across 125 questions and two dozen references. Open book helps with terminology, and accommodations may be available - check the current bulletin.

A real consideration on an exam this long and this reading-heavy.

The language

The examination is administered in English. Check the current bulletin for any language provisions, since these change and the bulletin is the authority.

Where open book helps

Terminology. An unfamiliar term in a question can often be resolved by finding it in a reference, which a closed-book exam would not allow.

That is a genuine advantage and it is worth building into your preparation deliberately - tab the definitions, not just the figures.

Where it does not

Reading speed. One hundred and twenty-five questions plus lookups across 330 minutes is a heavy reading load in any language, and heavier in a second one.

Which makes tabbing matter even more

Every lookup you can shorten buys reading time for the question stems. A candidate reading more slowly needs a better index than one who reads fast, and the index is entirely within your control.

Accommodations

Where a documented condition affects testing, provision may be available through the application process. What qualifies, and what evidence is wanted, is set out in the current bulletin.

Request before scheduling, since review takes time and the twelve-month window runs regardless.

Preparation that helps

Work practice questions in English from the start rather than translating. The vocabulary of the exam is the vocabulary of the references, and meeting it early is the point.
