In recent years, a growing body of evidence has confirmed what personal experience and intuition have long suggested: the quality of a child’s teacher has a profound and lasting impact on the child’s academic achievement. According to one expert, replacing just the least effective five percent of America’s teaching force with average teachers could catapult our nation’s K-12 education system from its current place among the worst performing in the developed world to among the top. Yet for complex reasons related to school culture, administrative inertia, and the time and cost associated with dismissing a teacher for poor performance, schools across the country continue to subject students to chronically ineffective teachers in considerable numbers.

In this Article we revive the argument, first raised in courts in the 1970s and 80s, that children assigned to ineffective teachers should be able to sue school districts under elementary principles of tort law, seeking relief in the form of reassignment to an adequate teacher and remedial education services. Courts initially rejected this “educational malpractice” theory of litigation due to the plaintiffs’ inability to establish basic elements of the negligence tort, pointing in particular to the lack of a workable standard of reasonable care (since little consensus existed regarding appropriate pedagogical methods) and problems showing proximate cause (since the effects of teacher quality on student learning were so difficult to prove).

The common law of torts, however, is designed to be judicially responsive to changing times and public policy considerations. And times have certainly changed: School officials today operate with access to unprecedented amounts of data concerning teacher effectiveness and teacher impacts on student learning that was wholly absent decades ago. These modern advances demand re-examination of the old reasons that courts provided for rejecting educational malpractice claims. To date, however, the academy has failed to undertake any such analysis.

This Article seeks to fill that gap. We argue that the recent advances in educational data substantially undermine the basic rationales offered by courts for dismissing the original educational malpractice lawsuits. In particular, unlike the initial era of educational negligence claims that proceeded principally under the theory that a school district should be liable for the negligent teaching practices of its teachers, we argue that a plaintiff student may state a claim against a school district for its negligence one step earlier: in its decision to assign the student to a classroom taught by a teacher whom school officials know to be chronically ineffective based on extensive statistical data concerning the teacher’s performance. For instance, schools now know with some degree of certainty, over a period of years, whether a particular teacher typically improves her students’ academic ability by more or less than a full grade level’s worth of gains. The worst teachers, it turns out, tend to produce paltry gains year-after-year. This data offers both an eminently workable standard of care for determining whether a school has been negligent in subjecting students to an incompetent teacher (indeed, some states such as New York require schools to classify teachers as “ineffective” on the basis of the student learning data), and also an evidentiary link establishing that the teacher is a proximate cause of the child’s lack of attainment.

In addition to setting the groundwork for this new educational malpractice claim, the Article also explores potential policy responses on the part of school districts who may seek to head off costly litigation brought by plaintiff students who have been assigned to in
