As far as I understand the ABRSM originally awarded the LAB diploma (Licentiate of the Associated Board); the LRSM (Licentiate of the Royal Schools of Music) was originally introduced for overseas students as an equivalent to the ARCM (Associate of the Royal College of Music) and the LRAM (Licentiate of the Royal Academy of Music).
In recent years, the diplomas of ARCM, DipRCM, LRSM (for overseas candidates) and LRAM have all been combined and replaced by the LRSM as it now stands. The LRAM is still available to internal RAM students. The DipABRSM and FRSM were introduced around 2000 I think. As I understand it, the DipABRSM replaced the Advanced Certificate. There was of course the GRSM diploma (Graduate of the Royal Schools of Music) for those who had completed the three year full-time course.

You are incorrect David!The RCM discontinued the ARCM diploma and no diploma has ever been combined.The ABRSM developed three new levels for worldwide use
