23-24 TESU catalog is here

[P226mem]

Also now is very clear which people of 16 years can come in (and limitations on first semester). I do not know if it was before but I have the impression that was worded differently.

That's a new direction for TESU.
yes, There are new age guidelines on undergraduate admissions. Still need to have completed high school. But Age waiver was changed from 18-20  to 16-20, and limited to 9 credits in that first semester: All students between 16 and 20 years of age will be limited to 9 credits in their first semester.

and looks like the accuplacer is no longer needed for those in age waiver category. and number of "credits" needed for age waiver was lowered as well.
