PTT online courses are categorised by one of three levels according to the depth of treatment they provide:
Level 1: Introductory:
PTT Introductory courses are designed for those with no previous experience or knowledge of telecommunications. These courses either provide an overview of a telecommunications subject or discuss the fundamentals of electronic communications. The study of general science at secondary (high) school is an adequate starting point for PTT Introductory courses.
PTT Introductory courses are suitable for those joining the telecommunications sector particularly as part of an apprenticeship programme.
Level 2: Intermediate:
PTT Intermediate courses are designed for technicians and engineers requiring an understanding of a certain aspect of telecommunications. Those planning to study an Intermediate course should have an understanding of the basic principles of electronic communications.
The depth of treatment provided by an Intermediate course is typically equivalent to level 3 of a UK national vocational qualification (NVQ). PTT Intermediate courses can be used to support the attainment of a Communications Technology NVQ at level 3.
Level 3: Advanced:
PTT Advanced courses are designed for those who require an in-depth treatment of a certain aspect of telecommunications. Such courses are suitable for system designers as well as those who will be responsible for the maintenance of the system described in the course.
Those planning to study a PTT Advanced course should have an understanding of the telecommunications principles which underpin the operation of the type of telecommunications system described in the course.
