A growing number of high schools in Maryland’s Montgomery County are making their cap and gown colors gender-neutral at a time of increasing recognition of students who are transgender or questioning their gender identity.

Three county high schools switched this year to graduation robes that are one color for all students, and five other high schools plan to do so for the class of 2016.

Some principals who still have robes assigned by gender say they allow students to choose colors. But some student advocates say that approach falls short for those questioning their identity and leaves some students feeling forced to come out when they don’t want to.

Here are high schools’ approaches, based on information from Montgomery County principals:

Damascus High School: Changed to one color for the class of 2015.
