KHS is fully accredited by the North Central Association for Accreditation (NCAA). Every five years the school is visited by North Central to assess the success of the school's individual school improvement plan. The professional and auxiliary staff members at the school complete an in-depth report which addresses one affective and one cognitive area that the school has chosen to address in an outcomes-based school improvement plan. This self-study is submitted to the North Central Association of Colleges and Schools for their review and evaluation.
