60 Minutes of Daily Reading Practice

Students read 30 minutes in school and 30 minutes at home. Quantity practice targets are set, monitored, and rewarded, ensuring every student adopts the independent reading routines of academically successful students.

Every Student Working at Appropriate Level

Using national standards for reading proficiency, both books and students are leveled based on what readers need to know and be able to do at each of the five developmental stages of reading acquisition, as outlined by No Child Left Behind. Learn more about our leveling system.

Connects Your Reading Initiatives to Common Core Standards

100 Book Challenge aligns all of your existing reading materials and assessment tools using one simple color-coded leveling platform, keyed to Common Core Standards, that students, teachers, and parents can understand and use to ensure every student is making expected progress towards proficiency.

Includes Parent Partnership Routines

As if they had stopped at the book store on the way home from school every day with $15–$50 to spend, each student arrives home every afternoon with 1 or 2 or 3 or more, trade books, hot off the press, that are part of a system designed for their achievement. The standards-based book sizing system and take home Skills Cards keep parents informed and participating in their children’s success.


Varsity en Español collections are designed for middle school students with reading levels 1st through 12th grades. Collections aim to be high-interest, with low levels staying as sophisticated as possible and higher level texts screened to eliminate content inappropriate for a middle school audience. With our standard-based leveling system, advanced students are never bored by the pace, while remedial students receive the support they need to catch up. The Varsity 100 Book Challenge Module includes books, educator tools, and student materials to create, support, and promote a reading culture in middle school classrooms.
