EXPOSED
This is a catch-all bucket — ophthalmic techs, EEG and neurodiagnostic techs, hearing aid specialists, orthopedic and dialysis-adjacent techs, sleep and perfusion assistants — and the modal worker spends most of the shift physically positioning patients, attaching electrodes or probes, calibrating equipment, and running protocol-driven tests. That hands-on layer is safe from software and from today's robotics; what is exposed is the interpretation, documentation, and reporting layer, where AI already reads waveforms, flags abnormalities, and drafts the tech note. Most of these roles carry certification or state registration rather than an independent license with personal liability, so the regulatory shield is thin and varies by state and specialty.
Mixed — a routine tier and a judgment tier. A 12 reflects the split inside the shift: applying a 21-lead EEG montage to a squirming pediatric patient, seating a patient at a slit lamp, or troubleshooting a dialysis machine alarm is not going anywhere, but the parts that fill your charting hours — waveform pre-reads, abnormality flagging, tonometry and visual field capture, sleep-study epoch scoring, hearing-threshold plotting — are already largely machine-generated, which is why this sits mid-band rather than at 16.
Hands-on in uncontrolled environments. 16 is earned by the fact that essentially nothing you do happens without the patient in front of you: measuring head circumference and marking scalp with collodion, holding a probe steady during an unpredictable movement, physically taking hearing-aid ear impressions, repositioning limbs for orthopedic casting — all in exam rooms, bedsides and ICUs where lighting, patient cooperation and anatomy vary every time, which no current robot handles.
Certification preferred, not legally required. 8 rather than 14 because ABRET, JCAHPO, IBHRE or state hearing-aid dispenser registration are usually the ceiling — real credentials with exams and CEUs, but the neurologist, ophthalmologist or nephrologist signs the interpretation and carries the malpractice exposure, and in several states parts of this bucket can be trained on the job with no credential at all.
Some relationship component. 10 sits above anonymous work because dialysis and sleep-lab techs see the same patients on a fixed schedule and hearing-aid specialists do repeat fittings where the patient asks for you by name, but the referring physician chose the department, not you, and most encounters are one-off diagnostic tests where the patient never learns your last name.
Meaningful discretion. 8 fits because you make real in-the-moment calls — recognizing artifact versus true epileptiform discharge and re-prepping the electrode, aborting a test when a patient's vitals shift, deciding a reading is unusable and repeating it — but the protocol dictates the montage, the sequence and the thresholds, and the diagnostic call and treatment decision belong to the supervising physician.
