Trustees with the Tuloso-Midway Independent School District are looking into the idea of hiring an independent consultant to analyze the air quality within the district's schools.

At Monday's scheduled meeting, school board members were presented with a report from the Texas Commission on Environmental Quality concerning the air quality within the school district.

The presentation was the second in a month to be brought before the school district, each of which addressed concerns with a November 2008 USA Today report that listed the TMISD as having some of the poorest air quality in that nation. A March 9 report was given to the board by an independent consultant hired by Flint Hills Resources.

After the TCEQ's report Monday, trustees briefly discussed the option of hiring a consultant for the district.

"In my opinion, it's a little risky," Gonzalez said. "To be effective, a study should (contain) a lot of measurements."

Superintendent Cornelio Gonzalez said he only had one option to bring to the board that was not suitable. It called for the district to pay about $12,000 for an 8-hour study at two campuses. However, a second proposal is still being worked on with a company in Portland, Ore., Gonzalez said.

Trustees then tabled the item for a future date, in order to allow Gonzalez time to obtain another proposal.

Also at Monday's meeting:

Trustees received a quarterly report from Kelly Services, which provides substitute teachers for the district.

The report showed that substitute usage for the district has increased since last school year, with 1,095 requests being made, as opposed to 930 in 2008. That is an increased cost of $100,970 for the district this school year, compared to $84,593 in 2008.

The number of days used also went up, from 833 in 2008 to 978 this year, according to the report.
