How to apply

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

Apply to NASCLA with the USD 65 application fee. Once approved you have 12 months and up to three attempts, and you book each sitting separately with PSI at USD 130.

Two organizations, in order. NASCLA approves you and PSI seats you.

Step one: apply to NASCLA

Submit an application with the USD 65 fee. Approval opens a window of 12 months.

Inside that window you may sit up to three times. That is a meaningful structure and it should shape your planning.

Step two: book with PSI

Once approved, schedule a seat at a PSI test center and pay the USD 130 examination fee.

The examination fee is per attempt. The application fee is per window.

Plan the window backwards

Three attempts in twelve months sounds generous. Book your first sitting in month two rather than month eleven, so a second and third attempt still fit inside the window you paid for.

What you need to apply

There is no published education or experience prerequisite for sitting the examination itself. Experience requirements belong to the state license rather than to the exam.

That surprises people who assume a commercial contractor exam must gate on experience. It does not; the state board does that separately.

After you pass

Your result sits in the NASCLA National Examination Database. You then request a transcript be sent to each state licensing agency you are applying to, at USD 45 each.

The transcript is what a state board actually receives. Passing does not automatically notify anybody.

Check the bulletin first

Fees and procedures change. The PSI Candidate Information Bulletin and NASCLA's own application page carry the current position, and both are free to read.
