I was OJTI at [multiple sectors] combined. Aircraft X came off RWI VFR looking for IFR to the west. Ceilings were low; so they stayed low to avoid. The MIA (Minimum Instrument Altitude) at RWI is 2;000. The pilot got his code assignment several times; but once he got it right; my developmental cleared them on course as filed and climbed. At that time they were at 2;500; and the MIA rose in that area to 3;200 due to a large antenna. I observed that the plane was a mile north of the antenna; and the flight was not in danger. Aircraft X then climbed unusually slowly to the west out of the high MIA.Stay on top of the trainee and don't let them do anything stupid.
ZDC Controller reported an aircraft was below the Minimum IFR Altitude.
