The sacrament of Initiation (Confirmation) normally occurs at tenth grade. (See the RCIA Page for Adult Initiation into the Church)
Per the Atlanta Archdiocese:
Youth ordinarily should have attended a Catholic school, a parish religious education program, or a home school religious education program for at least two years before enrollment in the free-standing parish Confirmation formation program. An exception to this policy may be made in such other circumstances as the Pastor deems appropriate. The Pastor is responsible for seeing that youth are properly prepared by examining them on the teaching they have received and the knowledge they have acquired. Compiled Policies no. 2.2(a); 1983 CIC c. 889.2.
