House committee substitute makes the following changes to the 1st edition.

Amends the proposed changes to GS 115C-12 to require that the school annual report card for each local school administrative unit include numerical school achievement and school growth scores (was, school achievement and school growth performance scores, and required the scores be on a scale of 0-100) and a separate corresponding letter grade (was, a separate corresponding performance letter grade) of A-F for both the school achievement and school growth earned by each school within the unit. Makes conforming changes to the proposed changes throughout the act to refer to school achievement and school growth scores and grades (rather than performance scores and grades), and eliminate references to the the numerical score scale of zero to 100.

Modifies the proposed changes to GS 115C-83.15, eliminating the proposed changes to and the existing language set out in subsection (d) regarding the calculation of performance scores for school achievement and school growth and corresponding letter grades (previous edition) or overall performance scores and grades (existing language). Instead, provides for separate and distinct scales for school achievement and school growth scores and corresponding grades. Enacts new subsection (b1) to now require the score for school achievement (determined pursuant to existing subsection (b)) to be used to determine the school achievement grade, according to the following scale and modified to add any other designation related to other performance measures, such as plus or minus: a score of 85 is equivalent to an A, 70 is equivalent to a B, 55 is equivalent to a C, 40 is equivalent to a D, and less than 40 is equivalent to an F (same scale as previously proposed in subsection (d)). Similarly, enacts new subsection (c1) to now require the score for school growth (determined pursuant to existing subsection (c)) to be converted by the State Board of Education (State Board) to a 100-point scale and used to determine the school growth grade, according to the following scale and modified to add any other designation related to other performance measures, such as plus or minus: a score of 90 is equivalent to an A, 80 is equivalent to a B, 70 is equivalent to a C, 60 is equivalent to a D, and less than 60 is equivalent to an F (different scale than previously proposed in subsection (d)). Makes conforming changes throughout the statute. Adds to the information that must be displayed prominently on a report card, accessible to the public on the Department of Public Instruction's website, the percentage of schools receiving a school growth letter grade of A-F earned by each school located within a local school administrative unit and statewide. 

Further amends GS 115C-83.17, definitions, to make conforming changes to statutory references. 

Makes conforming changes to GS 115C-83.16, concerning school performance indicators for the purpose of compliance with federal law. Adds a new requirement for the State Board to calculate the overall school performance score by adding the school achievement score and the school growth score earned by a school, with the student achievement score accounting for 80% and the school growth score accounting for 20% of the total sum, for purposes of compliance with specified federal law. Makes conforming changes. 

Makes further conforming changes. 

Changes the act's effective date, making the act effective January 1, 2020 (was, effective when the act becomes law), and applicable to school achievement grades, growth grades, and report cards issued based on data from the 2019-20 school year (was, 2018-19 school year).
