Centre requirements
Approval Centres already offering City & Guilds qualifications If your Centre is approved to offer the 2330 Certificate in Electrotechnical Technology you can apply for the new Level 2 Diploma in Electrical Installations (Buildings and Structures) (236502) approval using the fast track approval form, available from the City & Guilds website. Centres should use the fast track form if: • there have been no changes to the way the qualifications are delivered, and • they meet all of the approval criteria in the fast track form guidance notes. Fast track approval is available for 12 months from the launch of the qualification. After 12 months, the Centre will have to go through the standard Qualification Approval Process. The centre is responsible for checking that fast track approval is still current at the time of application. Centres NOT already offering City & Guilds qualifications To offer this qualification, new centres will need to gain both centre and qualification approval. Please refer to the Centre Manual - Supporting Customer Excellence for further information. Centre staff should familiarise themselves with the structure, content and assessment requirements of the qualification before designing a course programme.
Resource requirements Physical resources and site agreements Centres can use specially designated areas within a centre to develop practical skills and to assess the simulated practical assignments. The equipment, systems and machinery must meet industrial standards and be capable of being used under normal working conditions.

City & Guilds Level 2 Diploma in Electrical Installations (Buildings and Structures) (2365-02)
Human Resources Staff delivering this qualification must be able to demonstrate that they meet the following occupational expertise requirements. They should: • be technically competent in the area(s) for which they are delivering training and/or have experience of providing training • hold appropriate qualifications detailed in this handbook • have recent relevant experience in the specific area they are assessing • be able to demonstrate occupational competence in the areas of the Building Services Engineering (BSE) for which they are delivering training and/or assessment. This competence must be at a level equal to, or above, the level of training being delivered and must include current knowledge and skills of each industry (for which the assessment is taking place), its techniques, settings, legislative and regulatory requirements, codes of practice and guidance • have credible experience of providing training and/or assessment. Centre staff may undertake more than one role, eg tutor and assessor or internal quality assurer, but must never verify their own assessments.
Assessors must; • •
hold, or be working towards TAQA (A1/A2 – D32/33 updated) standards and continue to practice to these standards and possess CPD evidence of personally maintaining these standards, or have other suitable equivalent assessor qualifications endorsed by the Sector Skills Council and/or the Awarding Organisation.
Assessor Occupational Competence For the purposes of this qualification, occupational competence will be deemed to have been demonstrated by the verifiable evidence of one, preferably more, of the following: • a relevant sector qualification equal to or at a level above the training and/or assessment being delivered. Where earlier forerunner qualifications are held eg City and Guilds Craft or Advanced Craft Certificated, the assessor must demonstrate through CPD evidence a thorough knowledge of the qualification standards that they meet the required criteria • an up-to-date CPD record including relevant CPD qualifications. Assessors must either be able to demonstrate that they are registered and up-to-date with their registration with an appropriate approved industry registration body or have one or more relevant occupational qualifications to demonstrate that they can be regarded as occupationally competent in terms of assessing or verifying the qualification and the unit contained • a verifiable CV of industry experience and current knowledge of industry practice and techniques relevant to the occupational area in which they assess. This verifiable evidence must be at or above the level being assessed • a thorough knowledge and understanding of the qualification standards and requirements
City & Guilds Level 2 Diploma in Electrical Installations (Buildings and Structures) (2365-02)
7
Assessor continuing professional development (CPD) The occupational competence of assessors must be updated on a regular basis and be periodically reconfirmed via CPD evidence and quality assured by City and Guilds. It is the responsibility of the assessor to make use of opportunities for CPD such as industry conferences and events, access to trade publications and journals, SSC and professional/Trade Association events, at least on an annual basis to enhance and upgrade their professional development and technical knowledge. It is imperative that evidence records of these CPD opportunities/occasions are maintained and retained in a verifiable CPD record.
Guidance note Where questions arise about the occupational competence/qualification of an individual/trainer/assessor, these should be referred to the centre’s Qualifications Adviser for a decision. The Qualification Advisor may decide to refer the decision to the Portfolio/Group Portfolio Consultant for further consideration.
Candidate entry requirements City & Guilds does not set entry requirements for this qualification. However, centres must ensure that candidates have the potential and opportunity to gain the qualification successfully.
Age restrictions This qualification is approved for learners 16+.
Accreditation of prior learning (APL) Guidance on APL between this qualification and the 2357 qualification will be available on the website by the start of November 2012.

Delivering the qualification
Initial assessment and induction An initial assessment of each candidate should be made before the start of their programme to identify: • if the candidate has any specific training needs • support and guidance they may need when working towards their qualification • any units they have already completed, or credit they have accumulated which is relevant to the qualification • the appropriate type and level of qualification. We recommend that centres provide an induction programme so the candidate fully understands the requirements of the qualification, their responsibilities as a candidate, and the responsibilities of the centre. This information can be recorded on a learning contract. Induction should also be used to ensure that candidates are aware that this qualification does not make them qualified electricians. All candidates must complete a declaration confirming their understanding. This declaration can be found in Appendix 2.

Disclaimer
This document must be completed by the candidate and the tutor as part of the qualification induction. You have been enrolled on the Level 2 Diploma in Electrical Installations (Buildings and Structures) (2365-02). This is a qualification that tests both practical and knowledge based skills in a realistic working environment. When you have successfully completed this qualification you will be at an Improver/Electrician’s Mate level. In order to fully qualify as an Electrician you will need to fully meet the performance criteria as laid down in the National Occupational Standards put together by Summit Skills, the Sector Skills Council. This is covered in the City and Guilds 2357 Level 3 NVQ Diploma in Electrotechnical Technology. Your tutor/assessor will be able to explain how you may progress onto the City and Guilds 2357 Level 3 NVQ Diploma in Electrotechnical Technology. However, you should be aware that the relevant performance units will need to be carried out in industry. Completion of the 2357 will enable you to apply to join an industry graded or competent person’s scheme. I can confirm that as part of my induction the above statement has been explained and I understand that completing the City and Guilds Level 2 Diploma in Electrical Installations (Buildings and Structures) (2365-02) qualification will not make me a fully qualified Electrician.
