Vocabulary Fitness is a self-paced skill-building software program that helps students improve their vocabulary skills and provides teachers with measurable results. The program helps students master commonly confused and misused words.

After an assessment, students work on specific words, or learn in a mixed practice format. They receive help and contextual feedback. 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 the U.S. grades 4 through 9 (age 9 and up). The program can be used as well by beginner ESL and adult students.
