Last Week Tonight host John Oliver highlighted the standardized testing environment in many of today's schools, discussing the high stakes and stress often associated with testing in classrooms across the United States.

In contrast to recent calls for annual testing from some media outlets, Oliver spent nearly 18 minutes covering the current realities of standardized testing on the May 3 edition of HBO's Last Week Tonight, including high-stakes testing and value-added models that can negatively impact teachers and students. He also emphasized the connection to “publishing giant” Pearson, a company whom a Politico investigation found that “public officials often commit to buying from...even when there's little proof its products and services are effective.”

Oliver also drew attention to the recent battle over testing in Florida, and to the stress some students face as a result of standardized testing. He specifically pointed to test instructions in Ohio, which include procedures for students who vomit on the test booklet.
