Electacourse has a complete range of exam practice material to help electricians and students succeed in your sit-down (ie. not practical) Inspection and Testing exams.

Inspection and Testing has three exams 1: Multiple choice (including scenarios), 2: Written questions, and 3: Practical Assessment. These exams can be held at two levels – Initial Verification and Periodic Inspection & Testing:

  1. Initial Verification (2391-50)
  2. Periodic Inspection & Testing (2391-51
  3. Combined Inspection & Testing (2391-52) – this level is a combination of 2391-50 and 2391-52
2391-50 and 2391-51 are typically taken by students at college as they work towards their NVQ and qualification as an electrician.
2391-52 is often studied by qualified electricians or other skilled staff, who want to bring themselves up to date with Inspection and Testing regulations and practice.
