Literacy-based Promotion Act; revise to expand intervention and strategies for literacy proficiency among students in Grades 4 through 8.

HB 810 expands Mississippi's literacy program to cover grades 4 through 8, requiring schools to implement evidence-based reading interventions. The bill mandates teacher training in "science of reading" methods (excluding "three-cueing systems"), universal screening three times yearly, and identifies "Middle Literacy Support Schools" using reading data from state assessments. It requires targeted interventions for struggling readers, evidence-based instructional materials, and annual progress reports to the legislature. The law directly affects educators and students in grades 4-8 by establishing structured literacy approaches focused on phonics, decoding, and comprehension.
