I talked to the associate director of the Division of Management Information, Elizabeth Stern, and she provided a few reasons for the increase in the senior class. She said the increase is partially because the incoming freshman classes in the past few years have been larger than they were in the past. She also said that you can observe on the graph that there has been a spike in the number of juniors since 2012-2013.
“This has been caused both by increases in transfer students entering as juniors, and by increases in freshmen entering with large amounts of AP and transfer credits which quickly bumped them to junior class level,” said Stern.
She advised that we look into other areas of the profile to gain more information. She mentioned that lines 4600 and higher display that the graduation rate has stayed relatively stable.
