MIDDLETON, Wis. -- Teachers and students returned to Kromrey Middle School Friday morning after the school was closed for more than a week due to mold contamination.

The first day started smoothly, as parents dropped off students before the first bell Friday at 8:10 a.m.

The Middleton-Cross Plains Area School District said Thursday that the remaining two rooms at the school have been cleared after additional cleaning and testing.

The district said that the final air quality tests indicate that all of Kromrey Middle School is within the acceptable range and safe for students and staff. The two rooms, Room 150 and the kitchen, with higher mold count levels have come back with a mold spore count of zero, school officials said.

School officials said Room 150 will be ready for students Friday and no moves to another classroom will be necessary. Officials said the kitchen will need a day to organize and restock with food so the school is still planning to serve sack lunches on Friday. Regular school lunch will be available on Monday.

Middleton-Cross Plains Area School District Superintendent Don Johnson said staff members were working on Thursday to get their classrooms and the building ready for students.

School officials said they will continue to conduct periodic testing of air quality.

The school has been closed since last Tuesday after school officials found mold about a week before classes were set to start.

District leaders met with Kromrey Middle School parents Wednesday evening to discuss the effects of the mold problem.

At the meeting, school officials provided information on how the mold was discovered and removed around the facility and how the school plans to maintain a clean environment.

School officials also discussed how to make up the six days of lost class time, and the issue of make-up hours generated the most comments from parents at the meeting, WISC-TV reported.

"All her friends could be done with school, and there she is for another week and nobody likes that too much," said Robert Furreboe, whose daughter attends Kromrey Middle School.

"We have a couple proposals we're going to be taking. Both of them actually involve taking a couple days that are not currently on the schedule and also adding minutes to the days as well. We're going to make sure we meet state standards," Johnson said.

Essentially, the district has suggested taking two teacher planning days and making those actual school days as well as making the first semester school days 16 minutes longer.

That move not only makes up the lost days before the next semester, it would also preserve the two snow days that are already built into the school year, WISC-TV reported.

All of the comments and suggestions from Wednesday night's meeting will be presented next Monday to the school board, where a final decision on scheduling will be made. Johnson said the Wednesday meeting was recorded and will be available online by Thursday afternoon for those unable to attend. More information can also be found on the district website.
