About Saudi Skills Standards Saudi Skills Standards (SSS) is the national regulator and awarding body for Technical and Vocational Training (TVT) in the Kingdom of Saudi Arabia. It is jointly owned by the Human Resource Development Fund (HRDF) and the Technical and Vocational Training Corporation (TVTC), both of which report directly to the Minister of Labor. Its main purpose is to assure that TVT in the Kingdom meets national social and economic needs, in particular by ensuring that trainees entering the labor market have the skills, knowledge and competencies that employers demand. This will accelerate the progression of young Saudis into well-paid jobs and promising careers which is considered vital to the country’s future prosperity.

SSS has three main functions:

x Working with employers to develop and maintain National Occupational Skills Standards (NOSS) and TVT qualifications based on these Standards

x The testing and certification of trainees taking these qualifications

x The review and accreditation of training institutions

SSS is therefore a vital component in the creation of a modern training system in the Kingdom.

Associate Diploma and Diploma in Electrical Technology About this document This document provides the specification for qualifications in Electrical Technology at two levels.

Qualification name Qualification ID

Pre-requisite Date for first candidate registrations

Associate Diploma in Electrical Technology

ETUET-1-1-3 Achievement of:

1. Cambridge English KET, and 2. Cambridge International IT

Skills Certificate (Basic)

The document provides:

1. A rationale for the qualifications

2. The unit structure for each qualification with recommended learning hours for each unit and qualification

3. The detailed content of each unit in terms of:

a. Unit title and metadata

b. Unit purpose

c. Learning outcomes for skills together with performance criteria and scope (the skills scope should provide appropriate guidance for the types of equipment and other resources required for training)

d. Learning outcomes for knowledge together with scope (the skills scope should provide clear guidance in terms of the breadth and depth of knowledge the trainee needs to cover)

This document does not contain:

1. Assessment specifications or any sample assessment material – these will be directly based on the unit contents and will be provided in a separate, parallel document (scheduled for release in August 2014)

2. A training curriculum – this will be developed by the training provider

3. Learning materials or references to learning materials – these will also be developed or sourced by the provider

How these qualifications were developed These qualifications were developed over a 12-month period by experienced international technical training experts working closely with employer panels in the Kingdom. The development process consisted of the following stages:

National Occupational Skills Standards (NOSS)

1. Labor market research to identify priority occupations in the Kingdom that are appropriate for young Saudi trainees – in this case Electrical Technician

2. Analysis of the occupation to identify the main functions that employers expect their employees to be able to carry out

3. International research to identify best practice standards in each of these functions followed by validation by local employer panels

4. Tailoring of international best practice standards to ensure they are appropriate to the Saudi labor market and cultural and religious norms

5. Approval and sign-off by a Steering Committee consisting of representatives of major employers in the Kingdom

Qualification structures

1. Analysis of the NOSS to develop qualifications at two levels

2. Consultation with employer panels and local subject matter experts

3. Development of qualification units directly based on content of the NOSS

Qualification rationale The rationale for the design of these qualifications is as follows:

1. The qualifications adhere as closely as possible to the SSS NOSS for Electrical Technician, while offering coherent Associate Diploma and Diploma qualifications which have value in the labor market.

2. The Associate Diploma is more broad-based in content than the Diploma, covering essential skills and a working knowledge of electrical principles, processes and procedures. The Associate Diploma is a prerequisite for the Diploma but can also be a “standalone” qualification for trainees who do not wish to progress to the Diploma but want to enter the labor market with valuable set of skills, knowledge and competencies at a lower level.

3. The Diploma is more specialized, providing opportunities for trainees to develop and demonstrate skills in specific areas. Trainees will develop a more in-depth understanding of a wider range of electrical procedures and processes as well as increased confidence in practical understanding and application. Trainees successful in the Diploma should be able to enter the labor market as electrical technicians.

Recommended Learning Hours

Recommended Learning Hours (RLH) are similar to 'notional learning hours' or 'average learning time'. They describe an estimate of the time it would take a typical learner to achieve the learning outcomes in the unit or qualification. It is not the same as 'contact time', commonly described by ‘Guided Learning Hours’. RLH includes private study and preparation of course work, time spent during on-the-job training, revision for exams, research etc. as well as the Guided Learning Hours. For the Associate Diploma and the Diploma the relationship between GLH and RLH is that RLH = 1.2 x GLH. The approach of using RLH is increasingly used throughout Europe and many other parts of the world and is considered to be a fairer method of calculating student credit.

Employability and problem solving Both qualifications contain units that address three key areas of employability:

x Ability to manage own work

x Ability to work effectively as a member of a team

x Ability to work professionally in a company

The three employability units in the Associate Diploma cover the essential knowledge and understanding of how to work in an employment situation and will prepare the trainee for periods of work experience/on-the-job training.

The three employability units in the Diploma cover the necessary behaviors that employers expect and should be assessed while the trainee is undertaking on-the-job training.

The fourth area of employability that these qualifications covers is problem solving. This is an integral part of working effectively in Electrical Technology. This is embedded in the practical units in both qualifications.

In the Associate Diploma, students will be asked to address straightforward problems and apply techniques to consider possible answers. Whilst challenging, the problems posed will be at a level of complexity consistent with the skills and understanding required at this level.

For the Diploma, learners will be given task-based problem solving activities which encompass the range of knowledge they have gained throughout their program. This will measure two things:

1. Their ability to demonstrate understanding of more sophisticated concepts.

2. Their ability to apply that knowledge and understanding in solving complex problems and developing workable solutions.

In the Diploma this will typically encompass units such as:

• Install low voltage systems

• Understand low voltage machines

• Install control panel equipment

• Apply preventative maintenance

• Repair faults in low voltage electrical apparatus and circuits

• Verify compliance of low voltage systems
