Houghton Mifflin Harcourt

Houghton Mifflin Harcourt (HMH) is a major educational publisher whose textbooks and digital programs cover nearly every K–12 subject. While most products are marketed to schools, homeschool families often encounter HMH through used book sales, online course licenses, or district partnerships. The materials are typically rigorous and standards-aligned, with robust teacher editions and supplemental practice, which appeals to parents who want a conventional academic track. On the flip side, they can feel scripted and test-driven if followed rigidly, so many homeschoolers use them as a spine rather than a script. If you’re considering HMH, start with a single subject to see how it fits your teaching style.
