Northern Virginia Community College requires a minimum skill level for entry into the majority of its
mathematics courses as well as some of the science and computer science courses. The primary tool
for determining your skill level is an interactive computer generated test called COMPASS, developed
by American College Testing in Iowa City, IA.
You are strongly encouraged to review your skills prior to taking the test. The following pages will
give you a basic idea of what you can expect to see on the test.
The test is divided into five levels of material: prealgebra, algebra, college algebra, geometry, and
trigonometry. The test will begin with prealgebra questions.
As long as your answers are correct, the computer will keep giving you harder questions. Your
correct/incorrect answers will determine the number and type of problems that you will see. When the
computer program determines your placement level, the test will stop.
MATHEMATICS PLACEMENT TEST: WHAT IS THE TEST LIKE?
The following is a basic description of the type of material that should be mastered before
entering each course level. Simple examples have been given to illustrate the terminology.
These examples are not indicative of the complexity of the problems you will see on the
placement test. They merely indicate the ideas, which you should review before taking the test.

Pythagorean Theorem: ABC is a right triangle if and only if a2 + b2 = c2, where ∠ C = 90°; c is the
hypotenuse (the side opposite the 90° angle); a is the side opposite ∠ A; b is the side opposite ∠B.
In a right triangle with two 45° angles, the 2 legs are equal. The Pythagorean Theorem can then be
used to find the lengths of all sides, if you are given the length of any one side.
In a right triangle with 30° and 60° angles, the leg opposite the 30° angle is always half as long as the
hypotenuse. The Pythagorean Theorem can again be used to find the lengths of all sides, if you are
given the length of any one side.
An isosceles triangle contains two equal angles, and the sides opposite these equal angles have equal
length. An equilateral triangle has three sides of the same length, and all three angles measure 60°.
In any triangle, the sum of all the angles is always 180°.
Two triangles are called similar if their angles have the same measurements. In the two triangles,
sides opposite a pair of equal angles are called corresponding sides. The ratios of corresponding sides
