Whether your POST dispatcher score expires, and whether it travels
POST says a score on this test has no shelf life. Whether another department accepts it is that department's decision, not POST's — which is the same shape as the PELLETB and is what makes one sitting worth preparing properly for.
- Expiry
- None, per POST
- Proof
- A letter from the department that tested you
- Acceptance
- At the receiving department's discretion
- Retest
- A minimum of 31 days
The letter, and what it is worth
A department that administers the test is required to give you a letter stating your T-score. POST's applicant FAQ says other departments "have the discretion of accepting this letter as evidence that the candidate has met the POST standard" — so it is genuinely portable in practice and genuinely not guaranteed. Some agencies also set a currency rule of their own, asking that the score be dated within a certain period even though POST sets none.
Retesting
POST says you must wait 30 calendar days before taking the test again and may retake it a minimum of 31 days after your most recent administration. There is no published limit on how many times.
What that means for preparing
A score that never expires and travels between departments is worth more preparation than one tied to a single recruitment. The other side of it is that a low score you would rather not show also does not expire, which is the argument for taking it once you are ready rather than to see what it is like.
