1 What laboratories need to do in preparation for the new QCTO Materials Testers qualifications 27 th September 2016 NLA T&M Conference IMAGINE IT! MEASURE IT! St Georges Hotel, Centurion, Gauteng

2 What will be covered History of what's happened todate Philosophy of the qualification Overview of qualification Part quals Test Methods to be covered Internal training Internal mentors & assessors Internal vs external training programs External summative assessments External assessors The times lines going forward

3 History of what's happened todate & going forward Proposed curriculum submission made in Nov 2014 Submission on AWOL till Jan 2015 NLA approved as AQP August 2015 SLA agreements signed in Feb 2016 for DQP Through Educations committee in July 2016 QAS workshop August 2016 Revamped qual based on QAS workshop proposed on 9 th Sept 16 Public comment closed 12 th Sept Revised docs now at QCTO for final approval & submission to SAQA for registration Hopefully before year end Delays possibly a good thing in getting the qual back to the basics & not the Rolls Royce it initially was 2017 finalising all the assessment requirements & testing the system Setting up of theory modules by approved providers 2018 roll out of 1 st delegate registrations

4 Philosophy of qualification a slight deviation to the previous approach To train laboratory testers In the theoretical components appropriate to their working conditions For all commercial, quarrying, readymix, fluid bituminous products, asphalt, clients & contractors laboratories To understand the basics of what is required for the testing of civil materials And to be able to undertake the basic test methods applicable to their operation NB!! It is NOT meant to deem them competent on EVERY SINGLE POSSIBLE TEST METHODS these can be added over time by some approved means Or added into the course where required by a particular client

15 Access criteria & Internal training Entry requirements NQF Level 4 with mathematics 5 years active involvement in testing in civil engineering laboratory facility. Theory modules Accredited training provider thru NLA Course material approved thru QCTO/NLA FLC (pre-requisite) for access to external integrated summative assessment. Internal assessments Covers ALL theory modules ALL listed methods Record of results Theory modules Practical modules Work place modules Minimum pass mark 75 % across the board Successful statement of results allows access into external assessment

16 RPL Access to qualification: Accredited providers Approved workplaces may recognise prior learning against relevant access requirements. Readiness assessment Identify readiness to undertake qualification Identify gaps in knowledge Access to external integrated summative assessment: Accredited providers Approved workplaces must apply internal assessment criteria specified in related curriculum document to establish & confirm prior learning. Accredited Providers Workplaces Must confirm prior learning by issuing Statement of result Certified work experience record.

17 Accredited Providers, Mentors, supervisors, assessors & moderators Accreditation of providers done against criteria as reflected in relevant curriculum thru QCTO Facilitators, Assessors & Moderators competencies related to 10 years laboratory experience Education, Training and Development (ETD) related experience &/or qualification to facilitate, plan & conduct assessment &/or coaching competency as the minimum requirement. Practical modules Facilitator/learner ratio 1 to 15. Assessor/learner ratio 1 up to a max of 10. Work place modules Supervisor/learner ratio 1 up to a max of 10
