Write Source is a comprehensive K-12 writing and language arts curriculum that uses the Six Traits of Writing framework and a step-by-step process approach to develop students' composition skills from kindergarten through high school.
What is Write Source?
Write Source is a complete writing program spanning kindergarten through college level, developed over 40 years by authors Dave Kemper, Patrick Sebranek, and Verne Meyer. Originally published by Great Source (a Houghton Mifflin Harcourt division), the curriculum is now maintained by Thoughtful Learning, the company founded by its original creators. The program integrates grammar, usage, and mechanics within authentic writing contexts rather than teaching them in isolation. Its hallmark feature is the Six Traits of Writing framework—Ideas, Organization, Voice, Word Choice, Sentence Fluency, and Conventions—which provides both a teaching structure and an evaluation rubric.
Key Takeaways
- Covers K-12 with grade-specific handbooks including Writers Express (grades 4-5) and Writers INC (high school)
- Built on the research-based Six Traits of Writing evaluation framework
- Integrates grammar and mechanics into writing instruction rather than teaching them separately
- Upper-level materials are nearly self-instructional, requiring minimal parent preparation
- Homeschool packages include student text, teacher edition, SkillsBook for practice, and assessment materials
How the Curriculum Works
Write Source teaches writing through a consistent process: students study model compositions, analyze what makes them effective using the Six Traits, then follow step-by-step guidance to create their own pieces. Each writing form—narrative, expository, persuasive, and research-based—receives dedicated attention with tailored brainstorming techniques and development strategies. The curriculum spirals, introducing skills at age-appropriate levels and building on them each year. Grammar instruction flows naturally from writing contexts; students learn punctuation rules while editing their own work rather than completing disconnected worksheets. This integrated approach helps students see grammar as a tool for clear communication.
What's Included for Homeschoolers
The homeschool package typically includes the student handbook (a hardcover textbook doubling as a writing reference), teacher's edition with wraparound teaching suggestions, SkillsBook for grammar and mechanics practice, and an assessment book with rubrics. The student texts are written directly to learners, making them increasingly self-directed at upper levels. For middle and high schoolers, many parents find their involvement reduced to reviewing finished work and providing feedback. The handbooks also serve as reference tools students can use throughout their academic careers for grammar questions, citation formats, and writing guidance.
Best Uses in Your Homeschool
Write Source works particularly well for families teaching multiple children together since siblings can study the same writing forms at their respective levels simultaneously. The self-instructional upper-level materials suit busy parents or those less confident about teaching writing. However, the 2012 edition hasn't been updated to address modern elements like digital communication or current research formatting standards. Some families supplement with additional practice for high schoolers preparing for college-level writing demands. The program's strength lies in its comprehensive, systematic approach—ideal for families wanting a complete writing solution rather than piecing together multiple resources.
The Bottom Line
Write Source has earned its four-decade reputation by providing thorough, structured writing instruction that integrates grammar naturally and empowers students to evaluate their own work. The Six Traits framework gives both teachers and students a common language for discussing and improving writing. While the curriculum could benefit from updates addressing modern digital communication, its core methodology remains sound. For homeschool families seeking a complete, well-organized writing program that grows with their children from elementary through high school, Write Source delivers systematic instruction with minimal parent preparation time.
