"DeVos did not appear to understand the difference between testing that measures growth (how much a student has learned since their last test) and proficiency (whether a student has reached a certain baseline). She blanked on a major law protecting children with disabilities. At one point, she said guns might be needed in schools to “protect from potential grizzlies.” And yet the Senate was evenly divided over whether DeVos should be placed in charge of a cabinet agency that she seems to know little about. That is because the Senate is itself malapportioned to give voters in smaller states much greater voices than other voters. The 50 senators who opposed DeVos represent 179,381,386 people, while the 50 senators who supported her represent only 143,064,962 individuals."
