The BISD board of trustees will meet tonight and could approve the layoffs of more than 230 employees. Among the positions on a list that was released on Friday include a total of 27 math teachers, 18 science teachers, and 23 English teachers. Several band, choir, and art teacher positions are on the list as well. The layoffs are taking place to make up for a $25 million shortfall the district is facing going into the next school year.
