Cal. Educ. Code § 46200

(a) In the 1984–85 fiscal year, for each school district that certifies to the Superintendent of Public Instruction that it offers 180 days or more of instruction per school year, the Superintendent of Public Instruction shall apportion thirty-five dollars ($35) per unit of average daily attendance, exclusive of adult average daily attendance, the average daily attendance of pupils while participating in regional occupation centers or programs, and average daily attendance for pupils attending summer school. A multitrack year-round school shall be deemed to be in compliance with the 180-day requirement if it certifies to the Superintendent of Public Instruction that it is a multitrack year-round school and maintains its school for a minimum of 163 schooldays. Each school district that received an apportionment pursuant to this subdivision in the 1984–85 fiscal year shall add thirty-five dollars ($35) to the district’s base revenue limit per unit of average daily attendance for the 1985–86 fiscal year.

(c) For any school district that received an apportionment pursuant to subdivision (a) and that offers less than 180 days of instruction or, in multitrack year-round schools, fewer than the number of days required in subdivision (a) for multitrack year-round schools, in the 2001–02 fiscal year, or any fiscal year thereafter, the Superintendent of Public Instruction shall withhold from the district’s revenue limit apportionment for the average daily attendance of each affected grade level the sum of 0.0056 multiplied by that apportionment, for each day less than 180, or, in multitrack year-round schools, for each day less than the number of days required in subdivision (a) for year-round schools that the district offered.

(d) For any school district that received an apportionment pursuant to subdivision (a) and that offered less than 180 days of instruction as required in subdivision (a) in the 1985–86 fiscal year, to either the end of the final year of the teacher bargaining unit contract in force in that district on January 1, 2002, inclusive, or, if no teacher bargaining unit contract was in force in that district on January 1, 2002, to the end of the 2001–02 fiscal year, inclusive, and that provided the minimum number of instructional minutes in subdivision (a) of Section 46201 during all of the period applicable to the district pursuant to this subdivision, subdivision (c) shall not apply until the first fiscal year following the end of the applicable period of years.
