(a) Except as provided in paragraph (b) of this section, Head Start grantees funded or refunded after June 7, 1993, must comply with these requirements by such times in their grant cycles as new groups of children begin receiving services. This does not preclude grantees from voluntarily coming into compliance with these regulations prior to the effective date.

(b) With respect to the requirements of § 1306.32(b)(2), grantees that are currently operating classes in double session center-based options for less than three and a half hours per day, but for at least three hours per day, may continue to do so until September 1, 1995, at which time they must comply with the three and one-half hour minimum class time requirement.
