Before a business adopts tests in personnel selection, it should be decided that the increased cost and bother are likely to be offset by the savings that come from this additional selection procedure. Fairly accurate estimates of the cost of testing can be made, but in educational testing it is harder than in businesses to measure the results in dollars and cents. Most of the benefits appear in terms of pupil adjustment or in the student's post-graduate life. But in the absence of a capable counseling staff, the use of any tests at all may be an extravagance. Conversely, if a school is committed to a counseling service for its pupils, it is unwise not to provide the low-cost tools that can save the time of high-cost counselors.
