The traditional K-12 schooling model is a "bundled" product that provides parents with an all-in-one package of services: instruction, transportation, lunch, extracurriculars, and athletics, all delivered by one provider in one location: the school. Historically, parental choice has been limited to selecting from among different schools--neighborhood, magnet, or, for those with the means, private schools. In the 1990s, states started passing legislation that defined school choice in these "whole school" terms, with charters, vouchers, and scholarships providing families with alternatives to schools operated by their local district. However, in response to the widespread school closures sparked by the COVID-19 pandemic in early 2020, many parents opted for a pick-and-choose, customized approach to schooling that they hoped could fill gaps in the remote learning opportunities their local districts were providing. This article discusses the pros and cons of "The Great Unbundling" and the future challenges and opportunities for K-12 school systems.
