Results from two studies provided strong evidence for the validity of the HiSET tests, thereby demonstrating that HiSET is a well-developed battery of tests with passing and college and career readiness (CCR) standards that, when met, provide a pathway to postsecondary education, better employment opportunities and wages, and a better quality of life to those who are unable to experience a traditional high school education. Positive relationships exist between HiSET scores and both high school grades and ACT scores, including high levels of agreement between HiSET CCR indicators and ACT CCR indicators. Therefore, evidence supports the claim that HiSET scores are measures of high school equivalency, preparedness for middle skills jobs, and college readiness. Furthermore, there is evidence that passing the HiSET provides value to stakeholders. Passing the HiSET battery is associated with gaining academic and personal skills, college enrollment, employment gains (e.g., obtaining employment, obtaining more full-time employment, wage increases, and improvement in a job or position), and quality-of-life improvements.
