2018 - 2019 TISDO Arbiter Sports Registration

This season's Registration fee is $30.00

You may not attempt to take the test until at least 24 hours after you have successfully registered.

The 2018 - 2019 test consists of 50 questions drawn at random from a pool of 100.

Testees must score at least 80% (40 of 50) in order to pass.

Once a passing score has been achieved, you will be "locked out," i.e., you may not attempt to improve your score.

A maximum of five (5) attempts to pass the test are permitted.

Registrations will close at 2359 (11:59 PM) on October 31, 2018 and no extensions of any sort can be made.

Please keep in mind:  If you wait too long to register, it will be possible to Register and still not be able to actually take the test.  In such a case, there can be NO recourse, your Registration fee will be lost and you will not be registered for 2018 - 2019.
