How Many Students Really Graduate From High School? (WAMU): “Now, for the first time, the federal government is requiring states to follow a standardized method. As a result, DC’s public school graduation rate could drop by about 20 percent under the new calculation, according to the office of the state superintendent [...] The new method, called the adjusted graduation cohort rate, requires states to follow every individual child from the ninth grade on until he or she walks across the stage to receive that diploma. It takes into account students who change schools and get held back.” A new State Longitudinal Education Database will track each DCPS student from kindergarten through 12th grade through a special identification number. Could a more accurate picture of graduation rates be a critical step towards improving them?
