Traditionally, the Lake Bluff School Caucus and the Lake Forest Caucus have worked together to fill vacancies on the D115 School Board, through an informal agreement that 2 out of 7 total D115 School Board positions would be filled by Lake Bluff residents.

Sally Davis, a Lake Bluff resident, has been nominated for re-election to the Board of High School District 115 by the Lake Forest Caucus. In September of 2015, The Lake Forest High School District 115 Board of Education announced the appointment of Sally Davis to fill the board vacancy that resulted from Dave Schreiber's resignation, a Lake Forest Caucus designated vacancy.
