Hawaii Revised Statutes Division 1. Government § 302A-1139

(a) The department shall provide for the release of, and shall release, any pupil in any public school from attendance at the public school for a period not to exceed sixty minutes each week during the school year, on such days and during such school hours as the department shall designate, for the purpose of receiving religious instruction from the religious organization of the pupil's choice when the release is requested in writing by a parent, guardian, or other person having custody or control of the pupil. Actual attendance at the sessions of the religious instruction shall count as attendance at the public schools for all purposes where attendance forms the basis of computation.

(b) The privilege of this release shall be withdrawn by the department in case the pupil does not actually attend the sessions of religious instruction. No teacher of the public schools shall participate in religious instruction during the school hours for which the teacher is employed to teach in the public schools, and no public funds shall be used directly or indirectly for religious instruction, at any time when its use would otherwise be required in connection with the regular program of the school.
