While there is no set policy governing the test length, here are some best practices to keep in mind when designing your assessment:
Minimum of 25 Multiple-Choice Questions (MCQs) per test part
Maximum of 2 Constructed Response Items (CRIs) if the word length per item is 500 or more.
Total test time should be three hours or less (preferably less)
No more than 2 hours per test part (preferably less)
