1. 1.

A part-time common school student shall be counted as one-fourth, one-half or three-fourths of a full-time student if the student is enrolled in an instructional program that is at least one-fourth, one-half or three-fourths of the time a full-time student is enrolled as defined in subdivision (b) of this paragraph.

Fourth, fifth, sixth, seventh and eighth grade students must be enrolled in an instructional program that meets for a total of at least eight hundred ninety hours for a one hundred eighty-day school year, or the instructional hours prescribed in this section, including the equivalent number of instructional hours for schools that operate on a one hundred forty-four-day school year.

A full-time student shall not be counted more than once for computation of average daily membership. The average daily membership of a full-time high school student shall be 1.0 if the student is enrolled in at least four subjects that meet at least seven hundred twenty hours for a one hundred eighty-day school year, or the equivalent instructional hours prescribed in this section. The hours in which a student is scheduled to attend a high school during the regular school day shall be included in the calculation of the average daily membership for that student.
      3.
