Although introduced in 2000, the initiative - which sets an hourly rate for year-out students of £7.54 (£9.05 with London weighting) - has attracted very few practices.
The figures would see students on the equivalent of £16,290 in the capital and £13,570 in the rest of the country.
So far only eight practices have signed up to the Recommended Minimum Conditions of Employment. These include Malcolm Fraser Architects and Sheppard Robson.
Archaos co-chair Bonnie Chu said the campaign would not be aggressive, at least at the beginning.
'We really want to raise awareness and remind practices that this is there and that it should be taken up.
'I don't think it's being ignored, it's just that at the moment a lot [of practices] are unaware of it.
'Its not the right time to start blacklisting practices yet - we want to be more positive than that.'
