Trinity-St. Luke’s Lutheran School (TSL) is accredited through WELSSA – Wisconsin Evangelical Lutheran Synod School Accreditation. Initial accreditation was granted in the year 2000 following the completion of a self-study and validation by a visitation team. This process was repeated in 2007. Updates and long-range plans are completed annually for renewal of our accreditation through WELSSA. Copies of the visitation reports, annual updates, and the annual action plan are available through the principal.


TSL is also co-accredited through WRISA – Wisconsin Religious and Independent School Accreditation, and NCPSA – the National Council for Private School Accreditation. Through these accreditations TSL shows itself to be a school committed to continuous school improvement.
