The Latest on a suburban Chicago school board election (all times local):

4:30 p.m.

Experts say the results of a suburban Chicago school board election that was overshadowed by a transgender student bathroom policy could provide guidance to other districts.

Three school board candidates in the northwest suburbs who supported a plan to let a transgender student use the girls' locker room survived an election challenge Tuesday. Three parents who ran against them had campaigned on overhauling the policy.

Preliminary results for Township High School District 211 based in Palatine show two incumbents and a former school board member won.

Christopher Clark is a Midwest regional director for Lambda Legal. He says it could be a sign that public opinion will be supportive elsewhere.

However, a group that helped the challengers, Parents for Privacy, says the election wasn't only about the transgender policy. Co-founder Vicki Wilson says her group will continue to fight for bathroom privacy, including separate single-user bathrooms.

Some Chicago suburban school board members who approved a policy allowing a transgender student to use the locker room of the sex she identified with survived an election challenge mounted by angry parents.

The Palatine Township High School District 211 transgender policy prompted three opponents to run for the school board. Unofficial results late Tuesday show two incumbents and a former member supporting the transgender policy were elected.

More than 50 families calling themselves Parents for Privacy are suing the district in federal court, saying the transgender policy violates other students' privacy rights.

The opponents of the policy drew financial support from a donor who has given millions to conservative causes.
