In the Woodrow Wilson School’s first year without selective admissions, the number of students choosing to major in the school has nearly doubled. In April, 161 sophomores selected the school, compared to about 90 students who were admitted in past years.

The jump led to a steep drop for the politics department. Sixty-five sophomores chose politics as their major, compared with 122 members of the Class of 2014. Though the numbers for all departments were not released by the registrar, it appeared that the Wilson School would be the most popular major for the Class of 2015, with economics attracting 123 students and history drawing 77.

Extensive planning has prepared the Wilson School for the influx of students, said Elisabeth Donahue, associate dean for public and external affairs.
