The 2012-13 school year begins in Dickson County tomorrow. Teachers and administrators have been participating in staff development meetings and preparing classrooms to welcome students back. Director of Schools Dr. Danny Weeks said Tuesday that the maintenance department is waiting on a replacement part to repair one room air conditioner still not working. The school system spent the summer continuing with replacing heating and cooling systems under the second of two million dollar loans from the Energy Efficient Schools Initiative, including extensive work at Dickson Elementary School and the Dickson Middle School’s 6th grade campus. Weeks said there are still a couple of staff vacancies he is working to fill, but some likely will have to be filled with teachers on interim licenses due to high demand in certain subject areas. “Everything else is a go,” Weeks said in an email Tuesday morning. “We appreciate the community’s support, especially with the Make It Count campaign. We are ready and excited to open tomorrow.” Students will get the first break of the new school year Sept. 3 and 4 for Labor Day and a staff development day. A two-week fall break will begin Oct. 1.
