With most of the schools the age limits of attendance are fixed, and pupils may be admitted only within the time prescribed by the law. In some the age permitted is the common school age; in others pupils are admitted who are of "suitable age and qualifications," or "capacity;" and in some cases, no limits being set down, the matter seems to be left to the discretion of the authorities.[526] In schools where the limits of attendance are specified, the minimum age is usually six, seven or eight, while a few schools admit at five. In a few of the day schools, and in most of the oral home schools, children may be received as early as three, or even two, to make an early beginning in the use of speech, some of the home schools being designed expressly to receive children under five, or before the regular school period. The age limit for the completion of the school period is often twenty or twenty-one, while a few schools may keep pupils longer, as to twenty-five. The most frequent age period at present, where age limits are stated, is from six to twenty-one, but the period often begins and ends at other ages.[527] In some cases pupils are allowed to remain a certain number of years, but none beyond a certain limit, while in many the period may be extended two, three or five years, when it appears that the progress of the pupil justifies a more protracted residence.[528] Finally, it is to be noted that the limits of attendance have in general been lowered, and have been made to conform more and more with those of the regular schools.[529] FOOTNOTES: [519] Certain of the schools receive a few pay pupils, but these are usually from outside the state or are otherwise exceptionally provided for. Receipts from such sources are inconsiderable, and have little effect on the revenues of the schools. According to the Census of Benevolent Institutions of 1905, less than $55,000 came to the schools in this way, the greater amount being for pupils of other states. [520] The statutes of some states, as of Maine and Massachusetts, even go so far as distinctly to declare that no discrimination shall be made on account of wealth. On this subject, see Report of Clarke School, 1885, p. 8. [521] In Florida tuition at least seems to be provided free by the statute, and in Georgia free admission seems to be provided only for the indigent blind, while education is made free to all the deaf. On this subject, see _American Journal of Sociology_, iv., 1898, p. 51ff. [522] On this subject the superintendent of the Mississippi School addressed letters to heads of Southern schools, and found only two--those in Texas and Mississippi--having any requirement as to payment. In Mississippi there had been only two payments in the course of a considerable number of years. In the Texas school for the year 1909 we find the sum of $1,546 collected as a "reasonable amount" for board,--an unusual item in the receipts of a school.
