"Today is a day of tremendous sadness throughout the district," Dallas Independent School District Superintendent Michael Hinojosa said in a written statement.
"These teachers and counselors are people who devoted themselves to helping Dallas students, and we will do everything within our power to help them find new jobs."
The district laid off 375 teachers and 40 counselors and assistant principals Thursday, and transferred 460 teachers to other schools within the district.
The deficit was caused by a massive miscalculation in the budget, CNN affiliate WFAA-TV reported.
