By now, most students aiming to enter selective colleges this fall have sent in their applications. Some who applied early are in and done. Others must wait until late March or early April.

Below is a rundown of admission statistics so far for the Class of 2021. As of mid-January, the Massachusetts Institute of Technology had what appeared to be the lowest publicly disclosed admission rate for early applications among prominent schools: 8 percent.

Stay tuned. This table will be updated as the cycle progresses. Note that there are essentially three types of applications: early decision (ED), in which students must commit to enrolling if admitted; early action (EA), in which admitted students are allowed to weigh other offers until the spring; and regular, in which students get offers in the spring. Some colleges do not have ED or EA programs.
