This two-hour PRAXIS II test contains 50 multiple-choice questions and requires a graphing calculator. Forty-four percent of the questions deal with algebra and number theory, functions, and calculus. Here are the other question topics: measurement, geometry, trigonometry, data analysis and statistics, probability, matrix algebra, and discrete mathematics.

ETS’s Pedagogy exam consists of three essay questions, each worth 33 1/3 percent. One question deals with planning instruction, another with implementing instruction, and a third with assessing it. This PRAXIS II test is only one hour long. You may use a calculator if you like.

The PRAXIS II Mathematics: Proofs, Models, and Problems, Part I exam is composed of four exercises: two problems, a model, and a proof. The problems are each worth 20 percent; the model and proof are weighted at 30 percent each. Constructed responses—and a graphing calculator—are required. The test takes an hour to complete.
