SAFE
The paperwork layer of teaching — lesson plans, worksheets, rubrics, first-pass essay feedback, quiz generation, parent email drafts — is already being handled well by AI, and that is real time savings, not a real threat. What is not automatable is standing in a room with 28 sixteen-year-olds, holding attention, noticing who is quietly failing, and being the adult legally responsible for them; state licensure and in loco parentis duty of care make a credentialed human non-optional. The main risk is budget-driven class-size increases and a shift of some content delivery to software, which compresses headcount rather than eliminating the job.
Mixed — a routine tier and a judgment tier. A 12 rather than a 16 reflects that a large slice of the week — writing unit plans to state standards, generating differentiated worksheets, grading multiple-choice and even first-draft essays, logging grades, drafting parent emails — is genuinely machine-assistable now, while the irreducible core (running a Socratic seminar, redirecting a defiant student mid-lesson, re-teaching a concept three ways because you read the room) has no digital substitute.
Hands-on in uncontrolled environments. A high school classroom is an uncontrolled environment by any honest definition — 28 adolescents, hallway and cafeteria duty, breaking up a fight, chemistry lab supervision, fire drills and lockdown drills, bus and field-trip chaperoning — and the 15 rather than 19 only reflects that the intellectual work itself is done seated with a screen and a whiteboard.
Licensed human required and personally liable. State teaching licensure with content-area endorsement is a hard legal gate: an unlicensed adult cannot be the teacher of record, cannot sign off on credits toward a diploma, and cannot discharge in loco parentis duty of care — the 14 rather than 18 is because districts routinely fill seats with emergency and provisional certificates when they cannot hire, and personal malpractice exposure is far thinner than a physician's.
The human relationship is the product. Adolescents work for teachers they trust and stonewall ones they don't, so the relationship is the delivery mechanism for the content — but 15 not 19 because students are assigned to you by scheduling software, not chosen, and the roster resets every September regardless of how good last year's rapport was.
Meaningful discretion. State standards, pacing guides, district curricula and standardized testing calendars constrain a lot of the day, which caps this at 13 — but the calls that matter are yours alone and are made without a script: whether a bruise or a change in a kid's affect triggers a mandatory-reporter call, whether a plagiarism case goes to the office, whether to fail a senior short of credits, whether to escalate a suicide-risk disclosure.
