Most­ New York state LGBTQ students suffer discrimination at school — but only half report it to administrators, according to a new report.

The Gay Lesbian Straight Education Network study concluded that New York schools “were not safe” for LGBTQ children — and that only a third of their mistreatment complaints are ever addressed.

“In addition, many LGBTQ students in New York did not have access to important school resources, such as an LGBTQ-inclusive curriculum, and were not protected by supportive and inclusive school policies,” the report stated.

Nearly 90 percent of state ­LGBTQ kids said they regularly heard hostile slurs in schools and were subject to other forms of discrimination.

Some polled transgender students said they are denied the bathroom of their choice, are discouraged from engaging in public displays of affections, and are addressed with improper pronouns.

The annual study, which surveys LGBTQ kids in all 50 states, said action by New York lawmakers was “critical” to improve conditions.
