In 1906, the Carnegie Unit, or credit hour, was introduced to standardize U.S. public education. It defined the precise number of minutes students needed to learn a particular subject and the number of “credit hours” required to earn a high school or college degree. To be sure, at the dawn of the 20th century, this served an important purpose — standardizing an entirely unstandardized education system.
Today, the Carnegie Unit has infiltrated almost every aspect of American schooling. It defines how many minutes one must sit at a desk in a classroom or in front of a digital platform to learn. It shapes how schools and teaching are organized. It determines what is and is not assessed. It defines graduation requirements and dictates how schools are accredited. And it prescribes what goes on a transcript and influences who receives financial aid. In essence, the Carnegie Unit isn’t just hard-wired into the system; it is the system. And that needs to change.
