Topic Overview
The WJEC Entry Level Award in Preparing for Work (Entry 2) is a vocationally-related qualification designed to introduce students to the world of work. It covers essential skills such as understanding different types of jobs, workplace expectations, and basic job-seeking techniques. This qualification is part of the Foundations for Learning suite, which helps students build confidence and practical abilities for future employment or further study.
Students will explore topics like personal strengths and interests, how to search for job opportunities, and the importance of punctuality and teamwork. The course also includes creating a simple CV and practising interview skills. By the end, learners should be able to identify suitable job roles and understand what employers expect from workers at entry level.
This qualification matters because it bridges the gap between school and the workplace, giving students a head start in developing employability skills. It fits into the wider subject of Foundations for Learning by providing a structured pathway for those who may not yet be ready for GCSEs or higher-level vocational courses, ensuring they have the foundational knowledge to progress.

- Neglecting to use appropriate personal protective equipment (PPE) during practical tasks.
- Applying excessive force when fitting or removing components, causing damage.
- Misidentifying braking system parts, such as confusing brake pads with brake shoes.
- Confusing the function of the suspension system with the steering system.
- Failing to follow safety procedures when working under a vehicle.
- Overlooking the importance of correct tyre pressure.
- Misidentifying chassis components due to lack of hands-on practice.
- Confusing the vehicle chassis with the vehicle body, assuming they are the same structure.
- Failing to properly secure the vehicle on axle stands before attempting work, leading to safety risks.
- Misidentifying brake components as part of the steering system.
- Confusing the roles of springs and shock absorbers, thinking they are the same component.
- Failing to apply the handbrake before beginning any work on the vehicle.
- Mishandling tools or components, leading to lost or damaged parts during simple tasks.
- Confusing components from different systems, such as a steering rack with a suspension arm
- Failing to check tyre pressures before inspecting tread depth, leading to incorrect wear assessments
- Neglecting to wear appropriate PPE (gloves, safety boots) during practical tasks
- Misinterpreting a worn brake disc lip as a normal design feature
- Confusing the chassis frame with the vehicle body or subframe.
- Misidentifying coil springs as shock absorbers or vice versa.
- Neglecting to chock wheels and apply handbrake before lifting vehicle.
- Using incorrect jacking points leading to potential vehicle damage or instability.
- Over-tightening or cross-threading wheel nuts during refitting.
- Misconception: 'You don't need to prepare for an interview – just turn up.' Correction: Employers expect you to research the company, practise answers, and dress smartly. Preparation shows you are serious about the job.
- Misconception: 'A CV is just a list of your hobbies.' Correction: A CV should focus on skills and experiences relevant to the job, such as teamwork from school projects or volunteering. Hobbies are only useful if they show transferable skills.
- Misconception: 'All jobs are the same – it doesn't matter which one I choose.' Correction: Different jobs require different skills and offer different rewards. Matching your interests and strengths to a job increases satisfaction and success.
