37.--(_a_) The parent or guardian of, or person liable to maintain or having the actual custody of, any boy attending the School as a day pupil may claim by notice in writing addressed to the Head Master the exemption of such boy from attending prayer or religious worship, or from any lesson or series of lessons on a religious subject, and such boy shall be exempted accordingly, and a boy shall not, by reason of any exemption from attending prayer or religious worship, or from any lesson or series of lessons on a religious subject, be deprived of any advantage or emolument in the School or out of the endowment of the Foundation to which he would otherwise have been entitled. (_b_) If the parent or guardian of, or person liable to maintain or having the actual custody of, any boy who is about to attend the School and who but for this sub-clause could only be admitted as a boarder, desires the exemption of such boy from attending prayer or religious worship, or from any lesson or series of lessons on a religious subject, but the persons in charge of the boarding-houses of the School are not willing to allow such exemption, then it shall be the duty of the Governors to make proper provisions for enabling the boy to attend the School and have such exemption as a day pupil, without being deprived of any advantage or emolument to which he would otherwise have been entitled. (_c_) If any teacher, in the course of other lessons, at which any boy exempted under this clause is in accordance with the ordinary rules of the School present, teaches systematically and persistently any particular religious doctrine from the teaching of which any exemption has been claimed as in this clause before provided, the Governors shall, on complaint made in writing to them by the parent, guardian, or person liable to maintain or having the actual custody of such boy, hear the complainant, and inquire into the circumstances, and if the complaint is judged to be reasonable, make all proper provisions for remedying the matter complained of. _Examinations._ 38. Once at least in every two years there shall be, at the cost of the Foundation, an examination of the whole of each of the upper forms of the School by, or under the direction of, a University or other examining body approved by the Board of Education, with the assistance, if the Governors think fit, of any of the teaching staff of the School; and a report thereon shall be made to the Governors, who shall send copies of it to the Head Master and to the West Riding County Council and two copies to the Board of Education. Provided that the Board may, either generally or in any particular year, dispense with that examination as regards any of the upper forms. Once at least in every year there shall be an examination of the lower forms by the teaching staff of the School, and a report thereon shall be made to the Governors if they require it.
