(a) For the 1998-99 fiscal year, the Superintendent shall make the following computations to determine the amount of funding for each special education local plan area:

(1) Add the amount of funding per unit of average daily attendance computed for the special education local plan area pursuant to paragraph (1) of subdivision (a) of Section 56836.10 to the inflation adjustment computed pursuant to subdivision (d) for the 1998-99 fiscal year.

(2) Multiply the amount computed in paragraph (1) by the units of average daily attendance reported for the special education local plan area for the 1997-98 fiscal year, excluding average daily attendance for absences excused pursuant to subdivision (b) of Section 46010, as that subdivision read on July 1, 1996.

(3) Add the actual amount of the equalization adjustment, if any, computed for the 1998-99 fiscal year pursuant to Section 56836.14 to the amount computed in paragraph (2).

(4) Add or subtract, as appropriate, the adjustment for growth computed pursuant to Section 56836.13 from the amount computed in paragraph (3).

(b) (1) For the 1999-2000 fiscal year and each fiscal year thereafter, the Superintendent shall make the following computations to determine the amount of funding for each special education local plan area for the fiscal year in which the computation is made:

(A) Add the amount of funding per unit of average daily attendance computed for the special education local plan area for the prior fiscal year pursuant to Section 56836.10 to the inflation adjustment computed pursuant to subdivision (d) through the 2012-13 fiscal year, and for the 2013-14 fiscal year and each fiscal year thereafter, the inflation adjustment computed pursuant to subdivision (f), for the fiscal year in which the computation is made.

(B) For the 1999-2000 fiscal year to the 2018-19 fiscal year, inclusive, multiply the amount computed in subparagraph (A) by the units of average daily attendance reported for the special education local plan area for the prior fiscal year. For the 2019-20 fiscal year and each fiscal year thereafter, multiply the amount computed in subparagraph (A) by the units of average daily attendance upon which funding was based for the prior year.

(C) Add or subtract, as appropriate, the adjustment for growth or decline in enrollment, if any, computed for the special education local plan area for the fiscal year in which the computation is made pursuant to Section 56836.13 from the amount computed in subparagraph (B).

(2) For the 1999-2000 fiscal year to the 2018-19 fiscal year, inclusive, the amount of funding for each special education local plan area shall be the amount computed in paragraph (1).

(3) Subject to Section 56836.045, for the 2019-20 fiscal year and each fiscal year thereafter, the Superintendent shall determine the amount of funding for each special education local plan area, which shall be the greater of either subparagraph (A) or (B):

(A) The amount of funding computed for each special education local plan area pursuant to paragraph (1).

(B) An amount of funding computed as follows:

(i) Calculate the funded units of average daily attendance based on the average daily attendance reported for the special education local plan area for the fiscal year in which the computation is made or the prior fiscal year, whichever is greater.

(ii) For the 2019-20 fiscal year, calculate the amount of funding per unit of average daily attendance pursuant to Section 56836.11. For the 2020-21 fiscal year and every fiscal year thereafter, the amount of funding per unit of average daily attendance shall be the amount computed pursuant to this clause for the prior fiscal year multiplied by the inflation factor for the current fiscal year computed pursuant to paragraph (2) of subdivision (d) of Section 42238.02.

(iii) Multiply the funded units of average daily attendance computed in clause (i) by the amount of funding per unit of average daily attendance computed in clause (ii).

(C) If the amount of funding for a special education local plan area is determined pursuant to subparagraph (B) as of the second principal apportionment for the fiscal year in which the computation is made, the special education local plan area shall be funded pursuant to subparagraph (B) for each fiscal year thereafter.

(c) For the 1998-99 fiscal year to the 2012-13 fiscal year, inclusive, the Superintendent shall make the following computations to determine the amount of General Fund moneys that the special education local plan area may claim:

(1) Add the total of the amount of property taxes for the special education local plan area pursuant to Section 2572 for the fiscal year in which the computation is made to the amount of federal funds allocated for the purposes of paragraph (1) of subdivision (a) of Section 56836.09 for the fiscal year in which the computation is made.

(2) Add the amount of funding computed for the special education local plan area pursuant to subdivision (a) for the 1998-99 fiscal year, and commencing with the 1999-2000 fiscal year to the 2012-13 fiscal year, inclusive, the amount computed for the fiscal year in which the computations were made pursuant to subdivision (b) to the amount of funding computed for the special education local plan area pursuant to Article 3 (commencing with Section 56836.165).

(3) Subtract the sum computed in paragraph (1) from the sum computed in paragraph (2).

(d) For the 1998-99 fiscal year to the 2012-13 fiscal year, inclusive, the Superintendent shall make the following computations to determine the inflation adjustment for the fiscal year in which the computation is made:

(1) For the 1998-99 fiscal year, multiply the sum of the statewide target amount per unit of average daily attendance for special education local plan areas for the 1997-98 fiscal year computed pursuant to paragraph (3) of subdivision (a) of Section 56836.11 by the inflation adjustment computed pursuant to Section 42238.1 for the 1998-99 fiscal year.

(2) For the 1999-2000 fiscal year to the 2012-13 fiscal year, inclusive, multiply the sum of the statewide target amount per unit of average daily attendance for special education local plan areas for the prior fiscal year computed pursuant to Section 56836.11 for the prior fiscal year by the inflation adjustment computed pursuant to Section 42238.1 for the fiscal year in which the computation is made.

(3) For purposes of computing the inflation adjustment for the special education local plan area identified as the Los Angeles County Juvenile Court and Community School/Division of Alternative Education Special Education Local Plan Area for the 1998-99 fiscal year to the 2012-13 fiscal year, inclusive, the Superintendent shall multiply the amount of funding per unit of average daily attendance computed for that special education local plan area for the prior fiscal year pursuant to Section 56836.10 by the inflation adjustment computed pursuant to Section 42238.1 for the fiscal year in which the computation is being made.

(e) Notwithstanding any other law, for the 2013-14 fiscal year and each fiscal year thereafter, the Superintendent shall make the following computations to determine the amount of General Fund moneys that the special education local plan area may claim:

(1) Determine the total amount of property taxes for the special education local plan area pursuant to Section 2572 for the fiscal year in which the computation is made.

(2) Calculate the amount of funding computed for the special education local plan area pursuant to subdivision (b) for the fiscal year in which the computation is made.

(3) Subtract the amount computed in paragraph (1) from the amount computed in paragraph (2).

(f) For the 2013-14 fiscal year and each fiscal year thereafter, the Superintendent shall make the following computations to determine the inflation adjustment for the fiscal year in which the computation is made:

(1) Multiply the statewide target amount per unit of average daily attendance for special education local plan areas for the prior fiscal year computed pursuant to Section 56836.11 by the inflation factor for the current fiscal year computed pursuant to paragraph (2) of subdivision (d) of Section 42238.02.

(2) For purposes of computing the inflation adjustment for the special education local plan area identified as the Los Angeles County Juvenile Court and Community School/Division of Alternative Education Special Education Local Plan Area, the Superintendent shall multiply the amount of funding per unit of average daily attendance computed for that special education local plan area for the prior fiscal year pursuant to Section 56836.10 by the inflation factor for the current fiscal year computed pursuant to paragraph (2) of subdivision (d) of Section 42238.02.
