Bryan Adams has become one of the safest high schools in Dallas for LGBT teens. More than 100 students have joined the school’s gay-straight alliance.

GSA adviser Danielle Jones sent over a few pictures of the school’s National Day of Silence observation held on Friday.

According to GLSEN, National Day of Silence is a day of action in which students across the country vow to take a form of silence to call attention to the silencing effect of LGBT bullying and harassment in schools.

Founded in 1996, the Day of Silence has become the largest single student-led action towards creating safer schools for all, regardless of sexual orientation, gender identity or gender expression.
