This paper provides an overview of Reading One-to-One, a structured paraprofessional tutorial program designed to improve the performance of at-risk students in grades K-8, particularly low-income, minority, and second-language learners. The program builds on some elements of Reading Recovery and Success For All. The curriculum combines explicit instruction on decoding skills with the use of small books ranked by difficulty level. Each one-on-one tutoring session allows for about 40 minutes of instruction, 3 or 4 days per week. Tutors have a specific curriculum to follow, and each session is divided into 4 main parts: review, direct instruction, reading, and writing. Activities and specific reading materials correlate to the student's ability. The program has been implemented in elementary schools, middle schools, and community centers in 100 schools in 25 cities in 6 states, as well as in Mexico. Evidence suggests that students need a minimum of 70 sessions for any gain in reading level, and that the program is much more successful using paid tutors. Sections of the paper discuss background, philosophy and goals, program components, evidence of effectiveness, professional development and support, implementation, costs, considerations, contact information, and policy issues and questions.
