　　The annual Phi Delta Kappa/Gallup poll of attitudes towards public education releasedthis week found that a majorty of Americans feel t is important to put "a qualified,competent teacher in every classroom". Bob Chase, president of the National EducationAssociation (NEA), the main teachers' union, wasted no time in pointing out that this willrequire raising teachers' salaries so that more qualified candidates will enter the profession andstay there.

　　A study by two economists suggests that the quality of America's teachers has more to dowith how they are paid rather than how much. The pay of American public-school teachers isnot based on any measure of performance; instead, it is determined by a rigid formula based onexperience and years of schooling, factors massively unimportant in deciding how wellstudents do.

　　The uniform pay scale invites what economists call adverse selection. Since the mosttalented teachers are also likely to be good at other professions, they have a strong incentive toleave education for jobs in which pay is more closely linked to productivity. For dullards, theincentives are just the opposite.

　　The data are striking: when test scores are used as a proxy for ability, the brightestindividuals shun the teaching profession at every juncture. Clever students are the least likelyto choose education as a major at university. Among students who do major in education, those with higher test scores are less likely to become teachers. And among individuals who enterteaching, those with the highest test scores are the most likely to leave the profession early.

　　The study takes into consideration the effects of a nationwide 20% real increase in teachersalaries during the 1980s. It concludes that it had no appreciable effect on overall teacherquality, in large part because schools do a poor job of. recruiting and-selecting the best teachers.Also, even if higher salaries lure more qualified candidates into the profession, the overall effect on quality may be offset by mediocre teachers who choose to postpone retirement.
