An endorsement consists of a sequence of courses that are grouped together by interest or occupational skill. They provide students with in-depth knowledge of a subject area or a high-wage, high-skill, and in-demand occupation. Every career and technical education (CTE) Program of Study leads to an endorsement. 

Students are required to declare an endorsement, or chosen program of study, which will help in guiding course elective choices throughout high school. Students may earn a single endorsement, or multiple endorsements in the areas of: Arts and Humanities, Business and Industry, Multidisciplinary Studies, Public Service, or STEM (Science, Technology, Engineering, & Math). Students wishing to change their declared endorsement must follow the Keller ISD process and should see their assigned counselor. Endorsement change requests after the 10th grade year will be evaluated and may sometimes not be possible, depending on the pathway.
