From the report: "The study found no differences in student literacy scores based on timing or frequency of tutoring. Most schools (66 percent) offered tutoring during school and more than twice a week (64 percent). Rural schools were more likely to offer tutoring during school (92 percent) than were nonrural schools (47 percent). Most tutors were current teachers (55 percent) or retired teachers (12 percent). This study does not provide evidence of differences in student literacy scores based on tutor qualifications. More than half the students who participated in a full year of Project On-Track tutoring started the year with literacy assessment scores identifying them as most at risk for reading difficulties, and 42 percent of them improved to a lower risk category after one year of tutoring. Although this study uses descriptive methods and cannot assess effectiveness, the findings suggest that schools and districts using a highly structured tutoring program like Project On-Track might be able to exercise flexibility in when and how often tutoring is offered and by whom without compromising program quality and benefits to students."
