TRENTON — The city’s schools need everything from new playground equipment to extensive renovations to prepare for a district reconfiguration that will address overcrowding and create more middle schools, school officials said this week.

The district’s facilities committee, one of four committees working to implement the reconfiguration for the 2013-2014 school year, briefed school board members Monday night on their work to prepare buildings and secure supplies for the upcoming changes.

The restructuring will split up the district’s 21 schools into buildings for students in kindergarten through fifth grade, sixth to eighth grades and ninth through 12th grades, ending the use of K-8 schools.

The district will create two new middle schools and shuffle students and staff at several schools, including Cadwalader Elementary, which will become the new site of the district’s alternative middle school; Stokes Elementary, which will become a new early childhood center for preschoolers; and Jefferson Elementary, a shuttered school that will reopen to take in children who previously attended Stokes.

Several buildings, especially Jefferson, will need repairs and renovations to prepare for new student populations, according to Wesley Boykin, a co-chair of the facilities committee. For example, the district expects to use 17 classrooms at Stokes for preschool students and will need to have the classrooms adapted for younger students.

Stokes also needs new playground equipment, a computer lab at Hedgepeth-Williams will be converted to two new classrooms, Dunn Middle School needs upgrades for its athletic fields, and in-class bathrooms for younger students at Kilmer Elementary will be closed ahead of the arrival of the school’s new middle school population, among other work, the committee said.

The facilities committee must also make sure each school has enough desks and chairs, computers, textbooks and other supplies.

This month custodial staff and other workers began removing carpets and temporary partitions at Jefferson, where construction could start next month to ready the school for its reopening, the committee said. In the coming months, the district will ask moving companies to make bids to transport materials and begin packing up furniture and other equipment that needs to move to different buildings.

No cost estimates for the school renovations were given at the meeting, and district officials did not return calls for comment yesterday.
