In a different, better world I would agree with you. However even if placement isn't mandatory many students are either clueless or looking for guidance concerning which course is best for them. While it might be ideal to have an intelligent math literate individual discuss the issue with the student there often is neither the time or the money for such a solution. A placement test can assist in that process. It can also be motivational. It can show students that with a little hard work and self study that they may be able to succeed in a credit course rather than spend money on a developmental one. Secondarily, in a cash strapped, very large community college system there is often a shortage of seats for popular courses. Given that these courses are tax payer supported, don't we owe it to the taxpayers if not the students themselves to at least give priority to the better prepared students?
The bottom line is that a placement test is a tool and it is how you use it that counts the most.

I agree with Alain. Treisman called placement tests a scam. Let the student take whatever course they choose. They'll be fine.

I am none of the above. But, based on a very long experience, here are my conjectures on the issue:
-- Most students taking a placement test respond with a variable number of random answers, the less they "know", the higher the number of random answers.
-- Given a properly set up course, i.e. a course that does not deal in "topics" but in real mathematics, what the student "knows" is not that important.
-- The most important factor is that the student be able to devote a certain amount of time to the course.
-- The next most important factor is that the student be able to get information from a printed text.
-- The next most important factor is that the student know that asking questions is usually helpful to them.
Thus, rather than a placement test, I would advocate some sort of interview.
