Age and schooling certificate forms shall be formulated by the superintendent of public instruction, and except in cases otherwise specified by law must be printed on white paper. Every such certificate must be signed in the presence of the officer issuing it by the child in whose name it is issued. Blank certificates shall be furnished by the superintendent of public instruction upon request. Sec. 7766-1. The superintendent of schools shall not issue such certificate until he has received, examined, approved and filed the following papers duly executed: (1) The written pledge or promise of the person, partnership or corporation to legally employ the child, to permit him to attend school as provided in section 7767, General Code, and to return to the superintendent of schools the age and schooling certificate of the child or give notice of the non-use thereof within two days from the date of the child's withdrawal or dismissal from the service of that person, partnership or corporation, giving the reasons for such withdrawal or dismissal. (2) The school record of the child, properly filled out and signed by the person in charge of the school which the child last attended; giving the recorded age of the child, his address, standing in studies, rating in conduct, and attendance in days during the school year of his last attendance, and if that was not a full year, during the preceding school year. (3) Evidence of the age of the child as follows: (a) The birth certificate of the child (or duly attested transcript thereof) issued near the date of the birth of the child by the registrar of vital statistics of Ohio, or by a similar officer charged with the duty of recording births in another state or country, shall be conclusive evidence of the age of the child. (b) In the absence of such certificate, a passport (or duly attested transcript thereof) showing the date and place of birth of the child, filed with a register of passports at a port of entry of the United States; or a duly attested transcript of the certificate of birth or baptism or other religious record, showing the date and place of birth of the child, shall be conclusive evidence of the age of the child.
