PUBLIC SCHOOL FINANCE 235 The stimulation grants are four in number. A lump sum of $1,500 per school is granted to high schools that maintain teacher training courses, provided that the State Superin- tendent of Public Schools designatesonly one high school in a county to carry on this type of work. If more than one high school is approved in a county, the total state aid may not exceed $2,400, to be divided equally among the several schools.! A second form of stimulation grant consists of state aid to city normal schools, which are established in cities having a population of 75,000 or more by the board of education of the school district for the purpose of training teachers for the elementary schools of the city.” A two-year professional course is required before any city school district can obtain this form of state aid. The method of apportion- ment is complicated. In general, the factors used in de- termining the apportionment are (1) appropriations for teachers’ salaries in state normal schools, (2) the number of teachers employed in the public schools of the state, and (3) the number of teachers employed in the public schools of the particular city. In addition to the two forms of stimulation grant that have been considered, certain grants are made for the purpose of training teachers for negro schools. The method of apportionment is not specified by law and in practice is left to the discretion of the State Superintendent of Public Schools. The fourth form of stimulation grant is for vocational education. The state matches the federal grants per teacher under the Smith-Hughes Act in accord- ance with the provisions of that act. The compensation grants consist of special allotments for orphan tuition and for teachers engaged in instructing physically handicapped children. To be eligible for aid in the first case, a town or rural district must be educating fifteen or more orphan children supported by a philanthropic organization. The amount of state aid is $2.75 per month for each child in regular attendance, but the allotment may not exceed two thirds of the average annual instruction cost per pupil.
