Section 41601 Of Chapter 4. State School Fund—computation Of Allowance From California Education Code >> Division 3. >> Title 2. >> Part 24. >> Chapter 4.

. For the purposes of this chapter, the governing board of each school district shall report to the Superintendent of Public Instruction during each fiscal year the average daily attendance of the district for all full school months during (1) the period between July 1 and December 31, inclusive, to be known as the "first period" report for the first principal apportionment, and (2) the period between July 1 and April 15, inclusive, to be known as the "second period" report for the second principal apportionment. Each county superintendent of schools shall report the average daily attendance for the schools and classes maintained by him or her and the average daily attendance for the county school tuition fund. Each report shall be prepared in accordance with instructions on forms prescribed and furnished by the Superintendent of Public Instruction. Average daily attendance shall be computed in the following manner:
  (a) The average daily attendance in the regular elementary, middle, and high schools, including continuation schools and classes, opportunity schools and classes, and special day classes, maintained by the school districts shall be determined by dividing the total number of days of attendance allowed in all full school months in each period by the number of days the schools are actually taught in all full school months in each period, exclusive of Saturdays or Sundays and exclusive of weekend makeup classes pursuant to Section 37223.
  (b) The attendance for schools and classes maintained by a county superintendent of schools and the county school tuition fund shall be reported in the same manner as reported by school districts. The average daily attendance in special education classes operated by county superintendents of schools shall be determined in the same manner as all other attendance under subdivision (a). The average daily attendance in all other schools and classes maintained by the county superintendents of schools shall be determined by dividing the total number of days of attendance in all full school months in the first period by a divisor of 70, in the second period by 135 and at annual time by 175. For attendance in special classes and centers pursuant to Section 56364 or Section 56364.2, as applicable, the average daily attendance shall be reported by the county superintendents of schools, but credited for revenue limit purposes to the district in which the pupil resides.
  (c) The days of attendance in classes for adults and regional occupational centers programs shall be reported in the same manner as all other attendance under subdivision (a). The average daily attendance in those schools and classes shall be determined by dividing the total number of days of attendance in all full school months in the first period by a divisor of 85 in the second period by 135 and at annual time by 175.
