Introduction to the Praxis Biology: Content Knowledge Exam (5235)

The Praxis II Biology: Content Knowledge exam is a professional certification assessment offered to recent or prospective graduates of teacher preparation programs. In some parts of the U.S., candidates who intend to teach biology to secondary school pupils must successfully complete this exam in order to be certified as competent to do so.

To avoid confusion, a word should be said about the Praxis 5235 vs 5236. Similar to the 5235 Praxis, the Praxis Biology 5236 exam is a subject assessment on which a graduating educator demonstrates a basic knowledge of Biology that is sufficient to become a science educator. The Praxis II Biology: Content Knowledge (5235) test is noted be addressed to those who wish to teach secondary school pupils specifically. While more than 30 states use the Praxis 5236 test as a criterion for science teachers, only a few states require the more specialized Biology Praxis 5235.
