Lewisville ISD is experiencing a substitute shortage this school year. The district has been able to fill 57% of substitute needs in the district, said Melissa Cobb, who oversees substitutes at the district. That is a drop from 89% reported during the 2016-17 school year, according to the presentation Cobb gave the board during a Dec. 6 workshop. During the 2021-22 school year, 19,477 requests for substitutes were made with 11,252 of those requests filled, Cobb said. During the 2016-17 school year, 44,041 requests were made with 39,179 filled, she said. This is not a LISD-specific issue as other districts seeing similar issues because of the pandemic, Cobb said.
