8 Centre and scheme approval Centres wishing to offer City & Guilds qualifications must gain approval. New centres must apply for centre and scheme approval. Existing City & Guilds centres will need to get specific scheme approval to run this Certificate. Centre approval will normally be granted to centres already approved to offer assessments in related Electrical schemes. Full details of the process for both centre and scheme approval are given in Providing City & Guilds qualifications - a guide to centre and scheme approval which is available from City & Guilds regional offices (see page 20). City & Guilds reserves the right to suspend an approved centre, or withdraw its approval from an approved centre to conduct a particular City & Guilds scheme or particular City & Guilds schemes, for reasons of debt, malpractice or for any reason that maybe detrimental to the maintenance of authentic, reliable and valid qualifications or that may prejudice the name of City & Guilds. Operating procedures general requirements All Centres offering the qualification will have to meet the full requirements for the assessment procedures as detailed in this Handbook. This includes the provision of: appropriately qualified staff to invigilate the examination facilities for knowledge assessments to be undertaken at appropriate times under conditions required by City & Guilds. Invigilation Centres will be expected to provide invigilators for the examination procedures. The invigilator will be responsible for the conduct and integrity of the examination. The person(s) undertaking this role will need to: Be familiar with the content of the City & Guilds Conduct of examinations document Accurately observe the time allotted for the examination Read out the rules to candidates prior to commencement of the examination Ensure that all examination scripts are collected immediately after the examination and handed to the person responsible for despatching them Ensure compliance with all other regulations relating to the examination. Invigilators ideally will not be involved in training the candidates. However, where this is unavoidable, the trainer will not be allowed to be the only invigilator involved for that examination. 6

9 Assessment Procedures National standards and rigorous quality assurance are maintained by the use of City & Guilds set and marked written tests Quality assurance includes initial centre approval, scheme approval and the centre's own procedures for monitoring quality. Details of City & Guilds criteria and procedures, including roles of centre staff can be found in Providing City & Guilds Qualifications - a guide to centre and scheme approval. Details of the availability of assessments and of the general regulations for their conduct are given in the Directory of Assessments and Awards. If there is any inconsistency between the scheme regulations in this pamphlet and the Directory of Assessments and Awards, the Directory shall prevail. For candidates with particular requirements, centres should refer to City & Guilds policy document Access to Assessment. This also applies to candidates who wish to seek examinations in language other than English. The examination will be paper-based in the first instance although in the longer term it will be delivered through City & Guilds online systems. Security of Assessment material Centres must provide secure and lockable storage for: The question papers Interim storage of all question papers Responsibility for security The Centre Manager shall be responsible for ensuring the security of all examination materials, including the reference documents. He or she may nominate a named person to take charge of the examination materials, to be responsible for day-to-day security, to record the issue and return of examination material to storage after use. In addition to the nominated person the Centre Manager shall be the only person within the centre with access to the secure storage for examination material. The centre s storage provisions for examination materials, methods of recording issue and return will be examined by External Verifiers on centre approval visits, and failure to comply with the security requirements will have serious consequences for the centres ongoing approval as an assessment centre. On Line assessment requirements From summer 2004 the assessments will also be available on line through the City & Guilds GOLA system. Dual provision will continue for twelve months, however the frequency of paper tests will be reduced. Each test will comprise of multiple choice items in accordance with the test specifications provided. The entire test will be conducted via the candidate s VDU. All data relating to the assessment will be held by City & Guilds with results and performance feedback being delivered back to the approved centre. City & Guilds will continue to apply its rigorous quality control procedures to the production, 7

10 editing, marking, moderating and revision of all questions whilst at the same time applying a robust security system to prevent assessments being accessed or drawn down by unauthorised persons or for purposes beyond those authorised. GOLA registration Centres are required to register as a GOLA centre before any tests can be scheduled. The form for this is available from the website A centre only needs to register once for GOLA Further information There is a GOLA helpline number - centre enquiries and technical enquiries about GOLA can be directed to this number Centres can also gola@city-and-guilds.co.uk The following leaflets are available: A centre s guide to global on-line assessment A centre s guide to technical requirements for global on-line assessment A centre s guide to administering global on-line assessment A learner s guide to global on-line assessment. Centres looking for general information about GOLA or copies of the GOLA leaflets are advised to use the website 8

11 Test Specifications The assessments will be based on the Code of Practice and candidates will need a copy for the examination.

12 Results For the assessments there are two grades, PASS and FAIL. All candidates for City & Guilds certificates and assessments receive a Notification of Candidate Results giving details of their performance. Candidates who successfully complete the components of the certificate will automatically receive a City & Guilds Certificate. Centres will receive Notification of Candidate's Results and Certificates for their own candidates. Any correspondence is also conducted through the centre. Centres will receive consolidated results lists detailing the performance of all the candidates they enter, whether they are successful or not. 10

13 Designing courses of study Candidates for the various levels of certification will have come from very varied backgrounds and will have different employment and training experiences, ambitions and opportunities. Centres will therefore wish to a) conduct an initial assessment of candidates' achievements for the purposes of accrediting prior learning and determining level of entry to studies b) consider what learning modes and locations will best suit their candidates. In their initial assessment of candidate needs, centres will wish to consider a) what, if any, previous educational qualifications or training the candidate has b) what, if any, previous practical experience the candidate has which is relevant and from which relevant skill and knowledge may have been informally acquired. Note: Centres should ensure that prospective candidates possess adequate experience/knowledge appropriate to scheme requirements In their selection of learning modes and locations, centres will wish to consider the results of their initial assessments and the availability or provision of a) open or distance learning material b) workplace learning and assessment to be carried out co-operatively by the centre and the workplace c) co-operative working with other registered centres d) opportunities for co-operative learning between candidates for different certificates who need to acquire similar competences. So long, therefore, as the aims of the scheme are met, and the candidates acquire the necessary competences, the detailed structures of courses of study are a matter for the individual centre. Appeals and Equal Opportunities Centres must have their own auditable, appeals procedure. If a candidate is not satisfied with the examination conditions or a candidate feels that the opportunity for examination is being denied, the Centre Manager should, in the first instance, address the problem. If, however, the problem cannot be resolved, City & Guilds will arbitrate and an external verifier may be approached to offer independent advice. All appeals must be clearly documented by the Centre Manager and made available to the external verifier or City & Guilds if advice is required. Should occasions arise when centres are not satisfied with any aspect of the external verification process, they should contact City & Guilds regional or national office. Access to the qualification is open to all, irrespective of gender, race, creed, age or special needs. The Centre Manager should ensure that no candidate is subjected to unfair discrimination on any grounds in relation to access to assessment and to the fairness of the assessment. QCA requires City & Guilds to monitor centres to check whether equal opportunities policies are being adhered to. The City & Guilds equal opportunities policy appears in the Directory of Awards. 11
