Registered voters who reside within the school district boundaries are eligible to vote in any trustee election. Diboll ISD holds their trustee elections in May. There are no run-off elections. In order to be elected, the candidate must receive a plurality of the votes cast. Trustees serve staggered three year terms so that the entire Board is never up for election at the same time.

A local school board candidate must be:

1. a registered voter in the school district;
2. a resident of Diboll ISD for six months before the filing deadline; and
3. a resident of the state for 12 months before the filing deadline.

Trustees are required to participate in training activities accredited by the Texas Education Agency. These courses build on the skills and knowledge necessary for the trustees to ensure a quality education for the children in the district he or she serves. First year board members are required to receive 16 total hours of training in 3 different tier levels; experienced board members are required to receive 8 hours. Tier 1 training consists of orientation to the functioning of the local district and the Texas Education Code. Tier 2 training is team building and goal setting and includes the superintendent. Tier 3 training is continuing education chosen from different areas based on a needs assessment of the district or board member.

There are provisions in Board Policy whereby citizens may address the Board. Board Policy BED permits citizens to address the Board in an open forum on matters of general interest or concern. Patrons must observe established time limits (three minutes) when making their presentations. Citizens may not address topics regarding specific personnel in open forum. The Board may not discuss topics brought forth in open forum other than to recite existing policy or give factual information.

Board Policy GF relates to public complaints whereby citizens may appeal decisions to the Board that have been made at campuses or administrative levels. Addressing the Board at this level requires citizens to go through the established complaint procedures in order for their complaint to be posted on an agenda to be heard by the Board. Board policies are posted on the district website.
