The Arrowhead board voted to approve policy 89-12, described in the meeting materials as "restoring biological truth." The vote was taken by voice and recorded in the meeting transcript as an affirmative voice vote.

During the public comment period, Miss Silczyca told the board the policy would "falsif[y]" biology by excluding naturally occurring biological variations and by not accounting for intersex conditions. "Policy 89 12 restoring biological truth is biologically false and incomplete," she said, urging the board to consult medical and scientific experts before adopting the measure.

Board members who supported the policy framed it as a way to ensure consistency in district documents and said it would use biologically defined terminology in official records. One board member described the policy as bringing "clarity and consistency to our district by using biologically defined terminology and all of our official documents." Other members said the policy was intended to keep the board focused on academic priorities.

The motion to approve the policy was moved and seconded and then adopted by voice vote; the transcript records the motion as carrying with "Aye" from members. The board and administration acknowledged the public concerns and indicated the adoption provides a tool for district communications and documents but that its implementation and any impacts on curriculum would follow established review procedures.
