There is solid proof to state that board is singular
Example 1. This is the opening page of the official site of GMAC, the owners and administrators of GMAT
https://www.gmac.com/about-us/board-of-directors.aspxBoard of Directors
Our
Board includes representatives from member schools and industry.
You may see GMAC uses board with a singular verb.

When you refer to a single board, you call it board and it is singular; when you refer to more than one board, then you say
boards and then only it is plural as you may see from the highlighted part.
Example 2.This is the URL of the College Board, the administrators of the SAT:
https://www.collegeboard.org/aboutSee in the highlighted how the board describes itself.
The College
Board is a mission-driven not-for-profit organization
that connects students to college success and opportunity.
Founded in 1900, the
College Board was created to expand access to higher education. Today, the membership association
is made up of over 6,000 of the world’s leading educational institutions
and is dedicated to promoting excellence and equity in education.
Each year, the College
Board helps more than seven million students prepare for a successful transition to college through programs and services in college readiness and college success — including the SAT and the Advanced Placement Program. The organization
also serves the education community through research and advocacy on behalf of students, educators and schools.
What more proof is needed?
1. Instead of bothering to find if a topic is good or bad, let’s ponder whether there is at least some take-away. This topic at least wants to broadcast that a pronoun cannot reference two different nouns in the same topic.
2. We should be careful when we verbalize collective nouns. When in doubt, one should be able to substantiate with official stands.
So why not take it for its worth?
