SAFE
CTE teachers spend their days demonstrating welding beads, engine diagnostics, IV sticks on manikins, or knife work on a live line, and supervising teenagers around equipment that can injure them — none of which a language model or current robot does. The automatable slice is real but peripheral: syllabi, competency checklists, industry-certification study materials, safety quizzes, and grading rubrics. State teaching licensure plus an industry credential (ASE, AWS, ServSafe, CNA instructor approval) means a licensed adult must be in the room and is accountable for shop safety.
Mixed — a routine tier and a judgment tier. Teaching a 16-year-old to strike an arc, feel when a torque wrench breaks over, or read a patient's blood pressure by hand requires standing beside them and correcting hand position in real time — but the lesson planning, Perkins V documentation, competency tracking, and certification-exam prep that eat a third of the week are already being drafted by software, which is what holds this at 13 rather than 17.
Hands-on in uncontrolled environments. The classroom is a shop, kitchen, greenhouse, or clinical lab with live 220V circuits, running saws, hot oil, and pressurized gas — you are moving between stations, physically stopping a bad cut, and doing your own equipment maintenance and lockout/tagout, though it is still a school building on a bell schedule rather than a roof or a roadside, which is why it sits at 15 and not 19.
Licensed human required and personally liable. You hold a state CTE credential plus the industry ticket (AWS, ASE, ServSafe, CNA program approval) and you personally sign off that a student is competent to test — and when a student loses a fingertip on the table saw, the OSHA-equivalent state inspection and the district's incident review land on your supervision record, not just the principal's.
The human relationship is the product. The kids in your program self-selected into it and stay three or four years; you are the one writing the letter to the union apprenticeship coordinator, calling the shop owner who hires your graduates, and deciding which student gets the co-op placement — that network of local employer relationships is not transferable to whoever replaces you.
Meaningful discretion. You decide daily whether a specific teenager is ready to run the CNC unsupervised, whether a shaky student should be pulled from clinicals before they touch a real patient, and how to fail someone on a safety competency without ending their pathway — real calls with bodily consequences, but bounded by state frameworks and industry certification standards that define the endpoint, which caps it at 13.
