The Old School–New School controversy was a schism of the Presbyterian Church in the United States of America which took place in 1837 and lasted for over 20 years. The Old School, led by Charles Hodge of Princeton Theological Seminary, was more conservative theologically and did not support the revival movement. It called for traditional Calvinist orthodoxy as outlined in the Westminster standards.

Charles Hodge was a Reformed Presbyterian theologian and principal of Princeton Theological Seminary between 1851 and 1878.
