The heat has been playing havoc with the school week throughout the area.
Marshalltown schools went with a two-hour early dismissal Thursday, as did several other area school districts.
"All of our buildings have some air conditioning but not all air conditioning," said Pat Hemming, building operations supervisor with the Marshalltown Community School District.
Marshalltown Superintendent Marvin Wade said they monitor the schools throughout the day and especially take note when they don't cool off at night. The school district has in its long-term plan to have all schools completely air conditioned, but not an exact timeframe for the work.
"It's funding and what's on the wish list," Wade said of how they move forward with air conditioning.
Gladbrook-Reinbeck schools let out two hours early four days this week in a row beginning Tuesday through Friday, due to the heat.
"Obviously, it messes up the instructional time and other things," said G-R Superintendent Tim Kuehl. "Most of our facilities are not air conditioned."
Kuehl said some classrooms have been as warm as 90 degrees during the afternoon. He said it's odd that they started Aug. 15 and had no problem with heat that first week, and now record heat has forced them to shuffle their schedule in late August.
