Trustees of the Houston Independent School District (HISD) hope to change ethics rules involving vendor contracting.

According to the Houston Chronicle, the new rules would require trustees to disclose relationships with vendors, prohibit trustees from voting on contracts where a vendor contributed $500 or more to a trustee’s political campaign, and prohibit vendors’ contributions while bidding for HISD contracts.

Last October, similar ethics changes were discussed but not implemented by HISD. The trustees are expected to vote on new policies in September.
