The Delaware school board has approved a contract to replace ventilators at Delaware Hayes High School.

The contract will replace 21 ventilators on the second floor of the north academic wing of Hayes and will cost $333,130.

The money for the project will be taken from the district’s permanent improvement budget. The contract was awarded to Trane U.S., a Cincinnati-based HVAC contractor. School officials said the work will begin this summer and will be completed before classes resume.

Also at Monday’s work session, the board accepted the resignation of Julie German, principal at Dempsey Middle School, effective July 29. School Officials said German is resigning because she is moving out of state.

German has been the principal at Dempsey for two years and was assistant principal for two years before that.

The board approved a trip for students involved in JROTC this spring. JROTC students will participate in the National High School JROTC Drill Championships from April 28 to May 2 in Daytona Beach, Florida.

The board also approved a number of staffing changes including:

• Accepting the resignations of Andrew Lauer, a maintenance department employee at the tech center; Milton Bradley, a bus driver; and Karen Jackson, the school age child care director.

• Approving the employment of Ann Kolopus and Tracy Young, who will both serve as substitute nurses for the district, as well as Samuel Jaffee and Curtis Montgomery, who will work as assistant coaches for the Hayes baseball team.

Two Hayes students presented a kindergarten orientation video to the board.

Meg Vonada, a senior at Hayes High, and Molly Schul, a junior at Hayes, created the video after they were contacted by Joe Uher, elementary curriculum director for the district. Uher asked them to put together a video for parents to watch for more information about kindergarten.

The students said they went to every elementary school in the district and interviewed staff to give parents an expanded look at what day-to-day activities look like.

School officials said they were impressed with the video’s quality and said it would be shown at kindergarten information nights, embedded on the district’s website and shown at kindergarten screenings.
