Signing up for the reassignment hearings |

Response has been pretty light so far to sign up to speak at the student reassignment public hearings.
Only 37 speakers have registered so far for the four hearings. For Tuesday’s hearings, nine people have signed up to speak at Green Hope High and four people have signed up for Middle Creek High. Only three people have signed up for the Jan. 24 hearing at Knightdale High.
The biggest response so far has been for Thursday’s hearing at Leesville High School, with 21 speakers signed up now. A lot of Wildwood Forest Elementary parents are upset about begin added to the revised plan to be reassigned to Fox Road Elementary. It will be interesting to see if they throw the Riverside parents, who are slated to be reassigned from Fox Road to Wildwood Forest, under the bus.
Click here to sign up for the hearings. You can also call 850-1600. You can sign up until 11:59 p.m. the night before a hearing.
UPDATE
As of 4:30 p.m., no additional people had signed up to speak at Middle Creek or Knightdale. It's now up to 15 people at Green Hope and 23 at Leesville.
It's expected that people will be able to sign up on site on the day of the hearings. They'd go up after the people who registered in advance.
