The Group 2: Language acquisition (previously Second Language) subjects of the IB Diploma Programme consist of the nearly 80 additional languages offered and may be studied at the following levels: B (SL or HL), or ab initio (SL only). Latin and Classical Greek are also offered and may be taken at SL or HL. To earn an IB Diploma, a candidate must study an additional language, though a second Language A may be taken instead of studying that language as a Group 2 subject.
