This year, Yale Law School has extended their official application deadline from February 15th to March 1st. This is the second time they have officially extended that deadline. The first was in 2007, when the deadline was moved from February 1 to 15. In 2007 Yale Law also began to accept the February LSAT.
The new deadline will not affect the timing of actual admissions. Decisions will be released in mid-April.
The permanent adoption of this extension will depend upon the number of applicants during this extension.
