(a) Except as otherwise provided in this section, in fiscal year 2000–01 and prior, if the governing board of a school district offers less instructional time than the amount of instructional time fixed for the 1982–83 fiscal year, the Superintendent of Public Instruction shall, in that fiscal year, reduce that district’s apportionment by the average percentage increase in the base revenue limit for districts of similar type and size multiplied by the district’s units of average daily attendance.
(b) Except as otherwise provided in this section, in fiscal year 2001–02 and any fiscal year thereafter, if a school district that does not participate in the program set forth in this article offers less instructional time than the amount of instructional time fixed for the 1982–83 fiscal year, the Superintendent of Public Instruction shall withhold for that fiscal year, from the district’s revenue limit apportionment for the average daily attendance of each affected grade level, the amount of that apportionment multiplied by the percentage of instructional minutes fixed in the 1982–83 school year, at that grade level, that the district failed to offer.
(c) The Glendora Unified School District shall reinstate the sixth period, which shall be equivalent to at least 50 minutes of instruction, effective the start of the second semester of the 1983–84 fiscal year.
