science icon Biology End Of Instruction Practice Test

Students enrolled in Biology I must take the multiple choice End Of Instruction test. Students may request to retake the test once prior to graduation.

This multiple-choice test takes about 120 minutes to complete, including testing directions. The test is not strictly timed. Testing sessions for students who need more time can be extended. This additional time is available as an immediate extension of the testing session; it is not available as a separate session at another time.

Students who finish early need to make sure their work is complete and are encouraged to check and verify their answers prior to closing their test booklets. Students will not be allowed to reopen their test booklets once they have been closed for a given test session.

The Oklahoma State Department of Education provides this Test Blueprint that gives approximate numbers of test questions and the PASS objectives they cover.

Oklahoma does not provide detailed Biology I EOI sample tests. The practice test below has been compiled by this teacher as a aid for his students. Many of the questions on this practice test come from online tests provided by the state of Texas.
