More than 60 people are signed up to speak at today's hearing, which is being held not at the Wilson Building but at Eastern High School in Northeast D.C.
Mayor Gray says he's pleased by the strong response as it, in his words, "signifies that District residents from all wards and walks of life care deeply about the schools."
But that doesn't many those testifying later today are pleased with the city's proposed budget for each school.
Some schools are facing reductions in funding including seven of the city's eleven traditional public high schools.
Gray says he hopes the testimony of today's witnesses will help school officials, as they finalize the proposed budgets for next year.
The hearing kicks off at 5 p.m.
