The Institute for Catholic Liberal Education (ICLE)The Institute for Catholic Liberal Education (ICLE) is dedicated to saving and renewing our treasured Catholic school system, K-12, which is ever more vital in an increasingly “post-Christian” culture. To this end, ICLE offers conferences, workshops, site visits, teacher training, publications, and consultation services designed to give current and future teachers both theory and practice for immediate use. We work with entire dioceses, as well as parish schools, independent schools, and individual teachers.
