Please make sure to at the very least take a practice test before you sign up. You may take both subtests in the same sitting or in two separate ones; if you feel like you may need more time I'd recommend opting for two sessions.
Boston Public Schools also offers free courses to study for both halves of the test. Sometimes they offer vouchers to pay for the test as well so we recommend taking advantage of this!
This test is required for all certified educators and administrators.
Recommendations:
Review practice test to see how much further review you require. Utilize the workshop and tips.
