Units and Courses are identified by a "4+2" digit code. The four digits identify the subject and the two digits identify the level. A course can easily be identified as the code starts with the letter 'C', similarly a Unit will usually start with the letter 'D'. Access 1 level is always represented by '07' and Access 2 by '08'.
For example 'C003 08' is the course code for Art and Design at Access 2 and 'D9ET 07' is the Access 1 unit Handling Money.
In the Scottish Credit and Qualifications Framework (SCQF), Access 1 is SCQF level 1 and Access 2 is SCQF level 2.
