    City & Guilds Entry Level Award in Skills for Working Life (Entry 2)
    City & Guilds Entry Level Certificate in Skills for Working Life (Entry 2)

    Topic Overview

    The City & Guilds Entry Level Award in Skills for Working Life (Entry 2) is a foundational qualification designed to help students develop the essential skills needed to enter the workplace. This award focuses on building confidence, communication, and practical abilities that are directly applicable to real-world employment. It covers key areas such as following instructions, working as part of a team, and understanding basic health and safety in a work environment.

    This qualification is part of the Employability & Work Skills suite, which aims to prepare learners for the transition from education to employment. By completing this award, students demonstrate that they can carry out simple tasks under supervision, communicate effectively with colleagues and customers, and show awareness of workplace expectations. It is ideal for those who may need additional support to develop their employability skills and is often used as a stepping stone to higher-level qualifications or apprenticeships.

    In the wider context, this award helps bridge the gap between school and work, ensuring that all students, regardless of their starting point, have the opportunity to gain the skills employers value. It is particularly relevant for students with special educational needs or those who benefit from a more practical, hands-on approach to learning. The skills gained are transferable across various industries, making it a versatile and valuable qualification.

    Key Concepts

    Core ideas you must understand for this topic

    • →Following instructions: Understanding and carrying out simple verbal or written instructions accurately, such as 'put the boxes on the shelf' or 'clean the table after use'.
    • →Teamwork: Working cooperatively with others, sharing tasks, and taking turns. This includes listening to others and contributing ideas in a group setting.
    • →Health and safety basics: Recognising common hazards (e.g., wet floors, trailing wires) and knowing how to report them. Understanding the importance of personal protective equipment (PPE) like gloves or aprons.
    • →Communication: Using appropriate language and tone when speaking to colleagues or customers. This includes asking for help when needed and confirming understanding of tasks.
    • →Time management: Completing simple tasks within a given time frame, such as finishing a job before a break or end of shift.

    Learning Objectives

    What you need to know and understand

    • Be able to mix and lay concrete
    • Identify suitable materials for a given concrete mix
    • Calculate correct proportions of cement, aggregate, and water
    • Demonstrate safe manual mixing technique
    • Lay concrete into a prepared formwork or area
    • Level and finish the concrete surface using appropriate tools
    • Explain the importance of curing and protection

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly measuring and combining materials (cement, sand, aggregate, water) to achieve the specified mix ratio, using appropriate tools such as a gauge box or bucket.
    • Award credit for safely mixing concrete to a uniform, workable consistency free from lumps, using either a shovel and mixing board or a mechanical mixer if available, while wearing correct PPE (gloves, dust mask, safety goggles).
    • Award credit for transferring, placing, and roughly leveling the concrete in the designated formwork or area without spillage, then compacting and screeding to the required thickness.
    • Award credit for finishing the surface with a float or trowel to a smooth, even texture, and for cleaning tools and work area upon completion.
    • Award credit for correctly selecting and measuring materials according to specifications
    • Expect demonstration of a consistent, workable mix without excessive water
    • Look for appropriate use of personal protective equipment (PPE) throughout the task
    • Credit even spreading and levelling of concrete to the required thickness
    • Acknowledge correct application of finishing techniques to achieve a smooth surface
    • Check for evidence of cleaning tools and work area after use

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always don full PPE before handling materials: gloves, dust mask, safety goggles, and long sleeves to shield skin.
    • 💡Follow a clear method statement and double-check all measurements with your assessor before starting the mix.
    • 💡Use a consistent mixing rhythm and scrape the sides and bottom of the mixing container to incorporate all dry material.
    • 💡Keep tools clean and within easy reach; a clean trowel and screed board lead to a better finish and safer working practice.
    • 💡Always conduct a dynamic risk assessment before starting any practical task
    • 💡Memorise the standard mix ratios for general-purpose concrete
    • 💡Practice mixing small batches to develop a feel for the correct consistency
    • 💡Use a spirit level and straightedge to check surface evenness as you work
    • 💡Cover the laid concrete with polythene or damp hessian to control curing
    • 💡Tip 1: Use real-life examples in your assessments. For instance, when asked about teamwork, describe a time you helped a classmate or worked on a group project. This shows you can apply skills practically.
    • 💡Tip 2: Pay attention to key words in instructions like 'first', 'then', or 'finally'. These help you sequence tasks correctly, which is often assessed.
    • 💡Tip 3: In health and safety questions, always mention reporting hazards to a supervisor. This demonstrates you understand the correct procedure, not just the hazard itself.

    Common Mistakes

    Common errors to avoid in your coursework

    • Adding too much water to the mix, resulting in a weakened, crumbly concrete that lacks durability.
    • Failing to protect skin and eyes, leading to cement burns or irritation from contact with wet concrete or dust.
    • Not compacting or tamping the concrete sufficiently, leaving air pockets that compromise structural integrity.
    • Incorrectly estimating the volume needed, causing a shortage of material mid-pour or excessive waste.
    • Adding too much water, resulting in weak concrete mix
    • Neglecting to wear gloves, dust mask, or eye protection
    • Failing to prepare the base or formwork adequately before laying
    • Uneven levelling causing weak spots or excessive thickness
    • Rushing the finish, leaving an unprofessional surface texture
    • Misconception: 'You don't need to ask questions if you're unsure.' Correction: It's actually important to ask for clarification if you don't understand a task. Employers prefer you to ask rather than make a mistake.
    • Misconception: 'Health and safety rules are just for show.' Correction: These rules are in place to prevent accidents. Ignoring them can lead to serious injuries, so they must always be followed.
    • Misconception: 'Teamwork means doing everything together.' Correction: Teamwork involves dividing tasks and supporting each other, not necessarily doing the same thing at the same time.
