Trinity Lutheran School holds national accreditation through the Wisconsin Evangelical Lutheran Synod School Accreditation (WELSSA) and the Wisconsin Religious and Independent Schools Accreditation (WRISA). WELSSA is recognized and accredited by the National Council for Private School Accreditation. WRISA is a state chapter of the National Federation of Nonpublic School State Accrediting Associations which is recognized by the College Board and the Office of Non-Public Education, an office within the U.S. Department of Education. The accreditation process has been a useful tool to improve our school, ensure that our school meets or exceeds the state and federal standards, and allows our school to secure funds through grants and programs available to schools holding accreditation. Each year Trinity will submit an annual report to the accreditation agency detailing the progress of our 5-year strategic plan.
