How to Homeschool High School in Colorado (2026): Diplomas, Concurrent Enrollment, and College

In Colorado, you homeschool high school under the same notice-based program you already run, and Colorado sets no graduation requirements, so you decide when your student has finished and you issue the diploma. Two things stay in the picture at the high school level: the standardized testing Colorado asks for at grades nine and eleven, and Concurrent Enrollment, which lets your student earn tuition-free college credit.

This guide covers the diploma, the testing, Concurrent Enrollment, and college admission, and it sits alongside the full guide to homeschooling in Colorado.

Colorado High School Homeschooling at a Glance

To homeschool high school in Colorado, keep your notice on file, meet the testing checkpoints at grades nine and eleven, set your own graduation requirements, keep a transcript, and issue the diploma yourself. Colorado sets no graduation requirements and you graduate your student once your requirements are met. Through Concurrent Enrollment, students who are sixteen and older can take college courses that count for both high school and college, often at no tuition cost, though access usually runs through a participating district or school. The ASCENT fifth-year option ended after 2025-26. Confirm details at cde.state.co.us.

How Homeschool High School Works in Colorado

Colorado homeschooling runs on a notice to a school district and a testing or evaluation cycle, and both continue through high school. Colorado sets no graduation requirements, so you decide when your student has finished, you keep the transcript, and you issue the diploma. The two high school details to plan around are the standardized testing checkpoints and Concurrent Enrollment, both covered below. We cover the notice and the testing cycle in the Colorado homeschooling guide.

Because no state office reviews your high school plan, the record you keep is what carries weight later, whether that is a college application, a job, or a military enlistment. Colorado gives you the freedom to build that plan around your student, but the freedom only pays off if you use it to build something a stranger reading it later will find credible.

That freedom also comes with a couple of checkpoints that do not go away once your student hits ninth grade. The notice you filed with your district needs to stay current, and the testing cycle keeps running through grade eleven, so high school is not the point where you can set the paperwork aside. Treat those two obligations as fixed dates on the calendar, and build everything else, the courses, the transcript, and the extracurriculars, around them.

Set Graduation Requirements and Meet the Testing Checkpoints

Because Colorado sets no requirements, you set your own, often modeled on the state's graduation guidelines: four years of English, three or four of math and science, three of social studies, plus electives and the arts. Write the plan at the start of ninth grade and build the transcript as you go. At the same time, keep meeting Colorado's assessment rule: your student is tested at grades nine and eleven, with a composite score expected above the thirteenth percentile on a nationally standardized test. Keep those results with your records.

Choose a nationally standardized test that fits your student and administer it on schedule at both checkpoints, since the results become part of the documentation you may need to produce later for a school district, a college, or your own records. Use a free reading assessment to see where your student stands before you map the four-year plan, so the courses you choose match where your student is rather than an assumed grade level.

Concurrent Enrollment: Tuition-Free College Credit

Colorado's Concurrent Enrollment is the standout for high schoolers. A student who is sixteen or older can take college courses that count for both high school and college at the same time, often with no tuition cost to the family. Used strategically across the junior and senior years, a student can enter college with twenty to thirty credits already earned, sometimes as a full sophomore.

One practical point: Concurrent Enrollment is administered through school districts, so a homeschooler usually accesses it by enrolling through a participating district or school, which handles the paperwork and payment. Ask your district how homeschoolers join, since the process and available courses vary from one district to the next. Note that the ASCENT fifth-year extension of Concurrent Enrollment ended after the 2025-26 year, so plan around Concurrent Enrollment itself rather than counting on a fifth year to finish credits. We link the details in our Colorado homeschooling guide.

Start the conversation with your district by tenth grade, since some Concurrent Enrollment programs fill seats early and want a placement test score or prior coursework as evidence of readiness. Community colleges tend to have the most homeschool-friendly Concurrent Enrollment pathways, and a student who starts with one general education course in eleventh grade can often build to a full course load by senior year. The credit lands on an official college transcript from day one, which gives your student a verified record that stands alongside your own transcript when it is time to apply to a four-year school.

Issue the Diploma and Apply to College

When your student meets the requirements you set, you issue the diploma, dated and signed by you. Colorado does not issue a homeschool diploma, and yours is valid for college, employment, and the military, with no GED required. For college, pair the diploma with your transcript, SAT or ACT scores, and any Concurrent Enrollment grades, which arrive on an official college transcript and carry weight.

Colorado public universities admit homeschool graduates, and transferable college credit can shorten the path to a degree. Keep the diploma, transcript, and Concurrent Enrollment records together, since colleges and employers may ask for any of them at different points, and a student applying to a selective program may need course descriptions alongside the transcript. Link our planning guide here as a resource for planning the high school years and building a transcript that holds up under review.

Consider having the diploma notarized if your student is planning to enlist, since verification standards for homeschool credentials can vary by branch, and a notarized document tends to move through that process with fewer questions. For most families, though, the combination of a clear transcript, a signed diploma, and test scores is enough to satisfy any admissions office, employer, or licensing board that asks.

Choosing the right curriculum gets easier when you know what to teach, what to skip, and where to start.

Students With Learning Differences

If your student had an Individualized Education Program in public school, those services end when you homeschool, and that includes high school. You can build accommodations into your own program: extended time, modified assignments, or alternative formats, all noted alongside the relevant courses on your transcript. College disability services open once your student enrolls, including through Concurrent Enrollment, but those offices work from current documentation rather than an old public school file.

Plan documentation early, since colleges and testing accommodations can ask for recent records. An evaluation from a private specialist or tutor, done well before the junior year, tends to carry more weight with SAT or ACT accommodations offices and college disability services than records from several years earlier.

If your student is heading into Concurrent Enrollment, contact the disability services office at the partner college well before the course starts, since accommodations there are set up separately from anything in your homeschool records. A short lead time gives the office room to review documentation and put accommodations in place before the first class meeting rather than scrambling once the semester is underway.

A Note from Homeschool Teacher Guide: What This Really Means for You

Colorado keeps two things on your plate through high school, and both reward a little planning. Keep the testing checkpoints at grades nine and eleven, and file the results with your records. Then look hard at Concurrent Enrollment: from age sixteen your student can earn tuition-free college credit that counts twice, but because districts run it, you usually join through a participating district or school, so ask early how homeschoolers enroll. You issue the diploma, and it counts. Build a real transcript from ninth grade so college and Concurrent Enrollment both open easily. Our Colorado homeschooling guide covers the notice and testing cycle in full.

None of this asks for more than steady attention. Keep the notice current, hit the testing dates, and start the Concurrent Enrollment conversation with your district a year before your student is ready to use it. Families who handle those three things on schedule spend the rest of high school on the part that matters most: teaching.
