St. Bernadette of Lourdes School is accredited by the Middle States Association of Colleges and Schools, a recognized accrediting agency by the State of Pennsylvania, and maintains membership in the National Catholic Educational Association.
St. Bernadette School was granted accreditation for the period May 1, 2014 through May 1, 2021 from the Middle States Association of Colleges and Schools Commission on Elementary Schools Pre-Kindergarten through grade 8. The Middle States Evaluating Team commended "the Principal, faculty, and staff for providing an environment that nourishes strong Catholic values integrated into the curriculum and life of the school." The faculty was commended "for creating an atmosphere of genuine love, respect, and concern which helps each child attain a healthy positive self-image."
St. Bernadette School will be re-evaluated by the Middle States Association of Colleges and Schools Commission in fall 2021, which was re-scheduled from the prior school year due to the COVID-19 pandemic.
