Teach adults for one semester and you'll notice the pattern immediately: a GED prep class has someone three months from the test sitting next to someone who hasn't been in a classroom in twenty years. A community college continuing-ed course has a retired engineer next to someone who dropped out of high school. K-12 differentiation strategies assume a shared baseline age and shared prior years of instruction. Adult ed doesn't get that assumption for free — the range in one room can be enormous, and building around the "average" student means you lose both ends.
Why the K-12 planning playbook doesn't transfer cleanly
Most lesson-planning advice assumes students arrived through a fairly similar path — same grade, same feeder pattern, similar age-based development. Adult learners arrive with wildly different reasons for being there, different amounts of formal schooling, and different amounts of time between "last time I sat in a classroom" and now. A course plan built for one imagined "typical" adult learner will lose the people on both ends of that range in the first two weeks.
Building the plan around range, not around an average learner
Instead of planning for one typical student, plan explicitly for the spread:
1. Start with an honest intake, not a placement test that punishes. Ask AI to help draft a low-stakes opening activity that surfaces where people actually are without making anyone feel behind on day one. The goal is information for you, not a score for them.
2. Build core content once, entry points multiple times. The same lesson on a topic can have a "if this is new to you" on-ramp and a "if you've seen this before" extension built in from the start, rather than retrofitted later.
3. Ask AI to generate the same lesson at two reading/complexity levels and compare them side by side — you'll often find the "simpler" version is actually just as rigorous with cleaner language, which is a sign your original draft had unnecessary complexity, not necessary rigor.
4. Plan for re-entry. Adult learners miss more sessions than K-12 students, for real reasons — work schedules, childcare, transportation. Build a "missed last week" catch-up path into the course plan itself instead of treating every absence as a problem to solve on the fly.
Where our tools fit
Our [adult / continuing education course](/adult-education-course) tool is built specifically around this range-of-starting-points problem rather than assuming one shared baseline, and it pairs directly with our [differentiation plan](/differentiation-plan) tool once you need to build out the specific on-ramps and extensions for a given session.
What still needs your judgment
- Reading the room, literally. No AI-generated plan replaces walking in on day one and adjusting once you see who's actually there.
- Dignity over pace. The instinct to "catch someone up" fast can read as condescending. A good adult-ed plan lets people move at their own pace without announcing that's what's happening.
- Real logistics. Work schedules and life circumstances change week to week for adult learners in a way they usually don't for K-12 students — build flexibility into the plan, not just the content.
