ACT.org has sample questions for each of the three WorkKeys assessments, which are applied mathematics, reading for information and locating information. The website provides detailed explanations of the correct answers. Questions are divided into different levels of difficulty based on the types of skills involved in answering them.
District205.net also has free downloadable practice questions for ACT WorkKeys and provides other helpful resources for studying, such as formula sheets and test-taking strategies. Go.hrm.com has free WorkKeys sample tests, but the website only tells users if they answered questions correctly or incorrectly. It does not provide an explanation of how the correct answer was determined.
