Directs the Board of Education (the Board), in consultation with the Department of Education (the Department), to establish and implement standards for determining and recognizing student educational performance and academic achievement in the form of a weighted proportionality score for each school, to account for no less than five percent of such school's accreditation rating score or metric under the current school accountability system, for the purpose of identifying, accounting for in determining accreditation ratings, and addressing disparities in access to educational resources across racial, ethnic, and socioeconomic groups in public schools in the Commonwealth. The bill requires the Department to (i) develop a metric for calculating the weighted proportionality score for each school using certain variables calculated by the Department; (ii) develop a metric for calculating the improvement of a school's proportionality score received year over year; (iii) assign for each school based on such school's proportionality score a proportionality designation of "highly proportional," "proportional," "somewhat disproportional," and "highly disproportional"; and (iv) require any school board that contains within the school division a school assigned a proportionality designation of "highly disproportional" to develop and submit to the Department a remediation plan detailing the actions such school board will take to reduce disparities in access to education resources. The bill directs the Board to (a) amend its regulations to include as a school quality indicator the weighted proportionality score developed in accordance with the bill and (b) submit to the U.S. Department of Education within 90 days of the effective date of the bill any amendments necessary to its state plan pursuant to the federal Elementary and Secondary Education Act, as amended, that are necessary to implement the provisions of the act. Finally, the bill requires its provisions to be implemented beginning with the 2025–2026 school year.
