I agree your son should reconsider the tech school classes if he want to have a rigorous high school record and is aiming for a professional career in the a healthcare field.
He needs a heavy dose of science and mathematics for for pre-med. (Or pre-PA, pre-PT, etc)
He needs honors or above level chemistry, honors or above level in biology, honors or above level physics. Perhaps even anatomy/physiology if his high school offers it.
Most of his competitors/college peers will have had AP Chem, AP Bio, AP Physics in high school. Your son will be competing against these better prepared students in college for the A grades he needs to in order to become a creditable applicant for medical (or PA, PT, OT, AUD, etc) programs. Admission to medical school (and other healthcare professional schools) requires a high GPA. (For med school, the average admitted applicant had a 3.7+ last year.)
The tech program sounds like it will provide exposure to healthcare fields that do not require professional degree/advanced professional training. while he may find the exposure to these field interesting, if he’s interested in pursuing a healthcare career that requires post-graduate training, then he’s probably hurting his preparation.
