We have debated the issue of one night a week classes and the faculty (with
one or two exceptions) think it is academically unsound.

The night classes on our main campus are taught 2 nights a week and on a
satelite campus are taught 1 night a week. There seems to be little or no
statistical difference in student success rates of students in the two
formats. We have informally polled students in the 1-night a week classes.
Most of them think it is a hard way to take math, but overwhelmingly would
choose the 1-night a week format again because they deal with traffic,
parking, rushed dinner and baby sitter only once.
