Instructions

This is a STAAR Algebra II Assessment Test with multiple-choice and griddable questions.

Choose the best answer for each multiple-choice question. For griddable questions, enter your answer carefully.

You may use the scratch paper provided to work through problems, graph, or organize your thinking. Only answers submitted on the computer will be counted.

Each problem includes 2 hints. Make good use of them, but do not spend too much time on any one question. If you are stuck, eliminate choices, make your best selection, and move on.

Pay close attention to graphs, tables, units, rounding directions, and any restrictions given in the question.

The first 2 pages include reference materials and formulas you may need throughout the exam. They are for your own reference.
