Dr. Charles A. Prosser, the first National Director of Vocational Education, developed and publicized the
following sixteen theorems as a basis for sound and successful programs. Many attempts have been made
throughout subsequent years to re-phrase or update these statements, without success. There are certain
minimum standards without which one may not reasonably expect to operate a program of vocational
education and be effective generally in programs of either preparatory or extension education. There is
little reason to believe that these basic standards have changed materially since the early development of the
program. For this reason these sixteen theorems are being quoted with a short interpretation supplementing
each theorem.
