N.J. Stat. § 18A:7F-56
Security categorical aid for each school district and county vocational school district shall be calculated as follows:
SA = ((RE x $70) + (ARENR x ARSA)) x GCA
where
RE means the school district's or county vocational school district's resident enrollment;
ARENR means the district's number of at-risk pupils;
ARSA means the at-risk security amount; and
GCA is the geographic cost adjustment as developed by the commissioner.
For the 2008-2009 through 2010-2011 school years the at-risk security amount shall be calculated as follows:
for a district in which the concentration of at-risk pupils is less than 40% of resident enrollment, the at-risk security amount shall equal the district's (AR% x $10.15 x 100); and
for a district in which the concentration of at-risk pupils is equal to or greater than 40%, the at-risk security amount shall equal $406.
The security cost coefficients, $70, $10.15 and $406, used to determine the security amount, shall be adjusted by the CPI in the 2009-2010 and 2010-2011 school years as required pursuant to subsection b. of section 4 of this act. For subsequent school years, the cost coefficients shall be established in the Educational Adequacy Report, with adjustments by the CPI for each of the two school years following the first school year to which the report is applicable.
