Fast growth is nothing new in the Northwest school district. But the biggest boom might be yet to come.The district has the highest future lot total in the Fort Worth-Dallas area with more than 22,000 future lots planned, according to the district’s demographer. Bob Templeton, president of Templeton Demographics, told the Northwest school board at its Sept. 23 meeting that the 19,000-student district could expect to gain an additional 7,000 students over the next five years.New home construction in the district is booming, Templeton said, and should continue into 2014. Much of what’s driving the growth is a strong Texas economy that continues to outpace the rest of the country, Templeton said, Also at the meeting, the board approved Superintendent Karen G. Rue’s recommendation for the district’s new executive director of human resources. Kim Caley will begin her new position as a replacement is found for her current role as principal of Schluter Elementary School in Haslet.Caley, who has worked in Northwest since 1999, opened the elementary in 2011 as an America’s Choice School.“Hiring excellent teachers and staff is critical to the mission of Northwest ISD,” Caley said. “I am looking forward to working to ensure the human resources department continues to hire and preserve the finest quality educators and support staff to work in Northwest ISD.”Caley was also served as principal and, prior to that, assistant principal at Hughes Elementary School in Roanoke. She also served as an assistant principal and campus instructional teacher at Justin Elementary School. She has also worked in Grapevine/Colleyville and Denton school districts.Caley earned a master’s degree in education and a bachelor’s in business administration from Texas Woman’s University. She is pursuing a doctorate of educational leadership with a concentration in human resources from Nova Southeastern University. Caley is scheduled to graduate next summer.
