Mathematics Competencies Tested on the CBEST
The math test covers three major skill areas with each skill area addressing a number of subskills. An outline showing these skill areas and their major subskills is shown below.
1. Estimation, Measurement, and Statistical Principles
 Estimation and Measurement
 Understand and use standard units of length, temperature, weight, and capacity in the U.S. measurement system.
 Measure length and perimeter.
 Understand and use estimates of time to plan and achieve workrelated objectives.
 Estimate the results of problems involving addition, subtraction, multiplication, and division prior to computation.
 Statistical Principles
 Perform arithmetic operations with basic statistical data related to test scores (e.g., averages, ratios, proportions, and percentile scores).
 Understand basic principles of probability and predict likely outcomes based
on data provided (e.g., estimate the likelihood that an event will occur).
 Interpret the meaning of standardized test scores (e.g., stanine scores,
percentiles) to determine how individuals performed relative to other
students
2. Computation and Problem Solving
 Add, subtract, multiply, and divide with whole numbers.
 Add and subtract with positive and negative numbers.
 Add, subtract, multiply, and divide with fractions, decimals, and percentages.
 Determine and perform necessary arithmetic operations to solve a practical
mathematics problem (e.g., determine the total invoice cost for ordered
supplies by multiplying quantity by unit price, summing all items).
 Solve simple algebraic problems (e.g., equations with one unknown).
 Determine whether enough information is given to solve a problem; identify the facts given in a problem.
 Recognize alternative mathematical methods of solving a problem.
3. Numerical and Graphic Relationships
 Recognize relationships in numerical data (e.g., compute a percentage
change from one year to the next).
 Recognize the position of numbers in relation to each other (e.g., 1/3 is
between 1/4 and 1/2; 7<4).
 Use the relations less than, greater than, or equal to, and their associated
symbols to express a numerical relationship.
 Identify numbers, formulas, and mathematical expressions that are
mathematically equivalent (e.g., 2/4 = 1/2, 1/4 = 25%).
 Understand and use rounding rules when solving problems.
 Understand and apply the meaning of logical connectives (e.g., and, or,
ifthen) and quantifiers (e.g., some, all, none).
Identify or specify a missing entry from a table of data (e.g., subtotal).
 Use numerical information contained in tables, spreadsheets, and various
kinds of graphs (e.g., bar, line, circle) to solve mathematics problems.
