(a)
A pupil participating in a Concept 6 program shall not be credited with more than one day of attendance in any calendar day, except as permitted in Section 46140.
(b)
Average daily attendance generated at a regular elementary, junior high, or high school operated pursuant to this article shall be calculated as prescribed in subdivision (a) of Section 41601.
(c)
Notwithstanding Section 37640, subdivision (a) of Section 41601, and any other law, the number of days taught in one or more late entry makeup classes in which a pupil in a Concept 6 program is enrolled shall be disregarded, at the option of a school district, in calculating the number of days taught in the calculation of average daily attendance of that district for any school year, if the pupil entered the Concept 6 program after September 1 of that school year and the track in which the pupil is enrolled began instruction in July or August of that school year. For purposes of this subdivision, “late entry makeup class” is a class in which a pupil in a Concept 6 program is enrolled in order to compensate for the pupil’s late enrollment in that program. The number of days taught that are disregarded under this subdivision shall not exceed the number of schooldays occurring in the school year prior to September 1 in the track in which the pupil is enrolled, reduced by the number of schooldays, if any, occurring in a program operating under the traditional school calendar in which the pupil was enrolled in that school district in the same school year prior to the date upon which the pupil is first enrolled in the Concept 6 program.
