HMH
HMH (Houghton Mifflin Harcourt) is a major US educational publisher providing K–12 curriculum, textbooks, and digital learning solutions to schools nationwide.
What is HMH?
Houghton Mifflin Harcourt — rebranded as HMH Learning — is one of the oldest educational publishers in the United States, with roots tracing back to 1832. The company has spent the last decade pivoting from a traditional textbook publisher into a platform-based EdTech company, acquiring and building digital curriculum products including Ed: Your Learning Friend (the core digital platform), Math in Focus, Into Reading, and MATH 180. Districts that have purchased HMH curriculum programs access them through the Ed platform, which also includes teacher tools, assessment, and differentiation features.
The Ed platform serves as the delivery mechanism for HMH's core curriculum programs, providing students with digital readings, assignments, and interactive activities while giving teachers gradebook integration, data reports on class progress, and differentiation tools that assign students to appropriate instructional levels. Single sign-on through Clever or ClassLink is common in districts where HMH is one application among many in a broader EdTech portfolio. The platform supports Chromebook, iPad, and browser environments, which are the dominant device types in K-12 classroom settings.
When HMH Ed has problems, the impact is felt by students and teachers who depend on it for their core curriculum delivery — not supplemental tools but the primary materials for the lesson. Students cannot access digital readings or interactive assignments, forcing teachers to pivot to paper materials if they are available. Gradebook data fails to sync, leaving teachers without updated completion data for recent sessions. Single sign-on failures through Clever or ClassLink block students from accessing the platform entirely. Assessment features — which track student progress against learning objectives — return errors during result submission, losing the data teachers need for instructional planning.
Outage.gg tracks HMH platform status using real-time community reports from teachers and students. If the Ed platform is down, assignments are not loading, or SSO is failing, the live status page shows current impact.
