It is in the ACS Guidelines for Bachelor's Degree Programs from the Committee on Professional Training, page 6.

The number of students supervised by a faculty member or by a teaching
assistant in an instructional lab should not exceed 25.

=E2=80=8BI am interested in knowing if there is a recommended maximum number of undergraduate college chemistry lab students that can be supervised by one lab instructor in a typical teaching lab. =E2=80=8BI see a lot of references to 24 students per instructor for high schools, and was wondering if college labs have similar written guidelines about this particular issue, because I can't seem to find them.

An example would be a typical undergraduate general or organic teaching lab. If the lab room could hold 40 students based on square footage and fume hood space, is one lab instructor enough? What about one instructor with 2 adjoining lab rooms of 20 students each, for a total of 40 under their watch?

Thank you for any information.
