This study by Dr. Minda Aguhob of Scholastic Research & Validation examined the effects of READ 180 in high schools in Seminole County Public Schools. Researchers randomly assigned almost 300 9th and 10th grade students in 7 high schools to 12 READ 180 classrooms. Florida's Comprehensive Assessment Test (FCAT) Reading assessment results showed that after 6 months, 25% of READ 180 students showed an increase of at least one reading level. White students achieved greater gains than other racial subgroups; there were no significant differences by gender or socioeconomic status. Scholastic Reading Inventory (SRI) data indicated that 9th and 10th grade students demonstrated one year's reading growth. Students also showed improvements in reading grades. As a whole, READ 180 students had significantly higher gains than overall district gains.
