Sec. 7766-8.  Whenever an age and schooling certificate is applied for by a child over sixteen years of age who is unable to satisfactorily pass a test for the completion of the work of the seventh grade and who is not so below the normal in mental development that he cannot with further schooling and due industry pass such a test, an age and schooling certificate with the words “Conditional—­Schooling not Standard” printed or stamped across its face may be issued by the superintendent of schools to such child upon proof acceptable to such superintendent of schools of the following facts and upon agreement to the respective conditions made in writing by the child and by the parent, guardian or custodian in charge of such child: 

(A) Facts to be proved:

(1) That the child has been a resident of the school district for the last two or more years, has diligently attended upon instruction at school for the last two years or more, and is able to read, write and perform the fundamental operations of arithmetic.  These abilities shall be judged by the juvenile examiner or if there be none, by the superintendent of schools.

(2) That the child having been a resident of the school district less than two years, diligently attended upon instruction in school in the district or districts in which the child was a resident next preceding his residence in the present district for the last school year preceding his removal to the present district, and has diligently attended upon instruction in the schools of the present school district for the period that he has been a resident thereof.

(3) That the child has removed to the present school district since the beginning of the last annual school session, and that instruction adapted to his needs is not provided in the regular day schools in the school district.

(4) That the child is not sufficiently familiar with the English language to be properly instructed in the full-time day schools of the district.
