    OCNLR Level 1 Award in Progression
    OCNLR Level 1 Diploma in Progression

    Topic Overview

    The OCNLR Level 1 Diploma in Progression is a foundational qualification designed to equip students with the essential skills and knowledge needed to succeed in further education, training, or employment. This diploma covers a broad range of topics, including personal development, communication skills, numeracy, and digital literacy, all tailored to help learners build confidence and independence. By completing this qualification, students demonstrate their readiness to progress to Level 2 study or enter the workplace with a solid grounding in key competencies.

    This diploma is particularly valuable for students who may have struggled with traditional academic routes or who need additional support to develop study skills and self-management. The curriculum is structured around practical, real-world applications, ensuring that learners can immediately apply what they learn to everyday situations. Topics such as teamwork, problem-solving, and health and safety are integrated throughout, making the qualification highly relevant for both further education and employment.

    Within the wider context of the OCNLR qualifications framework, the Level 1 Diploma in Progression serves as a stepping stone, bridging the gap between basic skills and more advanced study. It is recognised by colleges, training providers, and employers as evidence of a student's ability to engage with learning and take responsibility for their own progress. Success in this diploma opens doors to a variety of Level 2 courses, apprenticeships, or entry-level jobs.

    Learning Objectives

    What you need to know and understand

    • Identify personal protective equipment (PPE) required for bricklaying tasks
    • Prepare mortar mix to the correct consistency and ratio for cavity wall construction
    • Demonstrate accurate measuring and marking out of the wall footprint
    • Apply bricklaying techniques to build a cavity wall section ensuring plumb, level, and gauge
    • Insert wall ties correctly at specified intervals and embed them in mortar beds
    • Inspect completed work for compliance with drawings and quality standards
    • Clean tools, equipment, and work area after use, disposing of waste appropriately
    • Be able to prepare for constructing a cavity wall., Be able to demonstrate skills and techniques used in constructing a cavity wall., Be able to construct a cavity wall., Be able to leave work area clean and tidy.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly donning and using appropriate PPE throughout the task
    • Expect demonstration of accurate mortar mixing achieving a workable consistency
    • Look for consistent brick bonding pattern and full mortar joints without excess snots
    • Assess that the cavity is maintained at the required width and kept free from mortar droppings
    • Reward methodical cleanup and proper storage of tools and unused materials
    • Award credit for demonstrating accurate setting out and leveling of the wall foundation using pegs, lines, and spirit level.
    • Award credit for correctly mixing mortar to an appropriate consistency and applying it to a consistent bed joint thickness of 10mm.
    • Award credit for installing wall ties at correct spacing (e.g., 900mm horizontally, 450mm vertically) and embedding them properly into mortar beds.
    • Award credit for building the cavity wall to gauge, maintaining uniform perpends and face plane with plumb alignment.
    • Award credit for inserting and bedding a damp-proof course at the correct height with appropriate laps and seals.
    • Award credit for clearing the work area of all debris, cleaning tools, and disposing of waste materials responsibly.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Review the project specification and drawings thoroughly before starting work
    • 💡Practice using a corner profile or gauge rod to maintain consistent course heights
    • 💡Regularly step back and visually inspect your work to catch alignment errors early
    • 💡Demonstrate verbal knowledge of why a cavity is used and how to keep it clear
    • 💡Always double-check your setting out against a specification or drawing before you start laying bricks.
    • 💡Use a gauge rod or tape measure regularly to ensure consistent course heights; record measurements in your portfolio.
    • 💡Photograph each stage of construction as evidence of process, including prep work, wall ties, and final cleaning.
    • 💡In the write-up, explain your choice of mortar mix and how it meets the specification for a cavity wall.
    • 💡Be prepared to answer questions on why cavity walls require weep holes and how they prevent moisture penetration.
    • 💡Tip 1: Keep a well-organised portfolio from day one. Label all evidence clearly and link it directly to the assessment criteria. This makes moderation easier and ensures you don't miss any requirements.
    • 💡Tip 2: Use real-life examples in your written work and discussions. For instance, when covering teamwork, describe a specific group project you did and what you learned. This shows deeper understanding and application.
    • 💡Tip 3: Don't underestimate the importance of reflection. Many units ask you to evaluate your own performance. Be honest about what went well and what you could improve – this demonstrates self-awareness and growth.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to use a spirit level at every course, resulting in a wall that is not plumb or level
    • Using a mortar mix that is too dry or too wet, compromising bond strength
    • Forgetting to install wall ties or placing them at incorrect spacings
    • Allowing mortar to bridge the cavity, which can lead to damp issues
    • Neglecting to clean tools immediately after use, causing material to harden
    • Failing to set out the wall accurately, leading to incorrect dimensions or misaligned corners.
    • Using mortar that is too dry or too wet, causing weak bonds or excessive slump.
    • Forgetting to install wall ties or placing them at incorrect intervals, compromising cavity integrity.
    • Neglecting to check plumb and level frequently during construction, resulting in a leaning or wavy wall.
    • Leaving mortar beds excessively thick or thin, which affects overall wall height and strength.
    • Not protecting the cavity from mortar snots and debris, which can create moisture bridges.
    • Misconception: 'This diploma is just a repeat of GCSEs.' Correction: While it covers similar skills, the focus is on practical application and building confidence, not just academic theory. Assessment is often portfolio-based rather than exam-heavy.
    • Misconception: 'I don't need to worry about attendance or deadlines because it's a Level 1 course.' Correction: Good attendance and meeting deadlines are key skills assessed in the diploma and are essential for progression to higher levels or employment.
    • Misconception: 'Digital literacy just means using social media.' Correction: Digital literacy includes using software like Word and Excel, understanding online safety, and evaluating information sources critically.
