Once you submit the bullying form, there are certain things that the principal must do:
4. Procedures for the Prompt Investigation of Acts of Bullying, Harassment, or Intimidation.
a) The principal or designee shall promptly investigate all reports of bullying, harassment, or intimidation and implement remedial measures and consequences as appropriate.
b) School administrators shall promptly notify parents of students involved in a bullying incident.
c) After the investigation has concluded, staff members
will conduct individual and private conferences with both the student who was bullied and the student who bullied to determine if the bullying, harassment, or intimidation has continued.

If I were you, I would start by sending an e-mail to the principal to ask about the status of these actions. Refer specifically to MCPS Policy JHF in your e-mail.
