# Math on the HISET®: What You Need to Know

The HISET® test assesses whether you have the knowledge equivalent to a high school graduate. Here are some basic facts about the math portion of the test:

• The math on this test corresponds to the math in a typical high school curriculum.

• The problems on the test do not require a calculator, although you may request one at the test center. You are not allowed to bring your own calculator.

• It is best to be proficient at basic mathematical operations without needing a calculator.

• While a formula sheet is provided, the distance-rate relationship, quadratic formula, and Pythagorean Theorem are not provided but are needed on the test.

• The word problems on the test emphasize applying concepts to real-world situations.

The HISET® test covers concepts from four broad content areas. Note the emphasis on algebraic concepts:

• Numbers and operations on numbers (19%)
• Measurement/geometry (18%)
• Data analysis/probability/statistics (18%)
• Algebraic concepts (45%)

In addition, the problems on the test require you to apply these process skills:

• Understand mathematical concepts and procedures
• Analyze and interpret Information
• Synthesize data and solve problems
Let’s outline the content in each area:
