Grammar Fitness is easy-to-use software that helps students improve their grammar skills and provides teachers with measurable results. The program implements strategies which help students cope with many troublesome points of grammar including usage, diction, idioms, grammatical relationships, and punctuation. After an assessment, students advance through the program at their own pace. They are able to track their progress through their progress-to-date and session scores. Students' scores are kept in a management system that allows teachers to view and print reports. Designed for students in U.S. grades 6 through 10 (age 11 and up). The program can be used as well by advanced intermediate ESL and adult students.
