Civil Service Math Test: Practice Questions, Answers and Study Guide

The civil service math test measures the practical arithmetic and problem-solving skills used in government jobs.

Math may appear on clerical, administrative, accounting, analyst, correction officer, court officer, public safety, revenue, social services, and technical civil service exams. The exact level depends on the exam title and official announcement.

Some civil service math sections focus on basic arithmetic. Others include percentages, ratios, averages, tables, schedules, word problems, algebra, geometry, statistics, or data interpretation.

This guide explains what may appear on a civil service math test, how to study, and how to practice with realistic sample questions.

Civil service math requirements vary by state, city, county, agency, job title, and exam announcement. Always check the official exam notice before relying on any math topics, calculator policy, time limit, number of questions, or passing score.
