Adult Secondary Education (ASE) consists of high school level instruction for adults (grades 9-12). Students are typically working toward a high school credential such as the national General Educational Development (GED) or the Wisconsin High School Equivalency Diploma (HSED).


The national GED program helps students prepare for and show mastery of the equivalent of a high school education. However, in Wisconsin the GED is not considered to be comparable to a high school diploma. The HSED is considered to be comparable.

To obtain a GED a student must pass tests in mathematics, science, writing, language arts, and social studies. Students prepare for the tests through self-paced individualized instruction and group instruction. Specific information on the GED/HSED can be found on the Wisconsin Department of Public Instruction website.

Technical colleges may also offer specific high school-level courses to individuals who may need a few credits to complete their high school diploma.
