Oral or written evidence of knowledge and understanding in: types and purpose of information sources; responsibilities regarding safety legislation. MERIT A candidate who achieves all performance criteria for all outcomes will be awarded a pass. A pass with merit may be awarded to a candidate who substantially exceeds the minimum requirements of the unit for practical competence in outcomes 3 and 4 and who consistently demonstrates at least four of the following: (a) (b) (c) (d) (e) (f) clarity and depth of descriptive responses; logical sequencing of work; optimum use of time and resources; high organisational ability; high motivation; high awareness of, and compliance with, safety requirements. ASSESSMENT In order to achieve this unit, candidates are required to present sufficient evidence that they have met all the performance criteria for each outcome within the range specified. Details of these requirements are given for each outcome. The assessment instruments used should follow the general guidance offered by the SQA assessment model and an integrative approach to assessment is encouraged. (See references at the end of support notes.) Accurate records should be made of the assessment instruments used showing how evidence is generated for each outcome and giving marking schemes and/or checklists, etc. Records of candidates' achievements should also be kept. These records will be required for external verification. SPECIAL NEEDS Proposals to modify outcomes, range statements or agreed assessment arrangements should be discussed in the first place with the external verifier. 5

7 HIGHER NATIONAL UNIT SPECIFICATION SUPPORT NOTES UNIT NUMBER: UNIT TITLE: MACHINE WOODWORKING: JOINTING TECHNIQUES SUPPORT NOTES: This part of the unit specification is offered as guidance. None of the sections of the support notes is mandatory. NOTIONAL DESIGN LENGTH: SQA allocates a notional design length to a unit on the basis of the time estimated for achievement of the stated standards by a candidate whose starting point is as described in the access statement. The notional design length for this unit is 40 hours. The use of notional design length for programme design and timetabling is advisory only. CONTENT/CONTEXT The candidate successfully completing this unit should achieve a level of competence of someone who from time to time will be expected to carry out machining operations for the production of jointed components, including assessing the capability of individual machines, interpreting machining requirements and carrying out pre-machining preparations. The adopting of safe working practices should be emphasised throughout. APPROACHES TO GENERATING EVIDENCE A candidate-centred, resource-based learning approach is recommended. Throughout the unit the candidate should work individually to produce evidence of competence. Evidence for the preparation of machines and the formation of joints could be integrated with other units. ASSESSMENT PROCEDURES Centres may use instruments of assessment which are considered by tutors/trainers to be the most appropriate. Examples of instruments of assessment which could be used are: Outcome 1 Restricted response Questions could be set in line with the performance criteria as follows: (a) capabilities of machines - 3 (b) limitations of machines and equipment - 3 (c) selection of ancillary equipment and attachments - 4 (d) specification of tooling and equipment - 4 7

8 Satisfactory achievement of this outcome could be based on the candidate producing, for a pass, at least two correct responses to each of (a) and (b), plus at least three correct responses to each of (c) and (d) and, for a merit, a further two correct responses. Outcome 2 Restricted response Questions could be set in line with the performance criteria as follows: (a) selection of machines - 4 (b) selection of attachments and ancillary equipment - 4 (c) setting-up and operating procedures - 4 Satisfactory achievement of this outcome could be based on the candidate producing, for a pass, at least three correct responses to each of (a), (b) and (c) and, for a merit, a further two correct responses. Outcomes 3 and 4 Practical exercise Practical tasks could be set to cover both outcomes with a specification given to candidate. Satisfactory achievement of the outcomes could be based on the candidate meeting the requirements on the specification and satisfying an observation checklist regarding work methods and activities for both pass and merit standards. PROGRESSION This unit forms part of the programme for the Advanced Certificate in Machine Woodworking. Candidates successfully completing the Advanced Certificate will be able to progress to the HNC in Construction Practice. Each unit is a separate part of the framework of units for the award and units are not necessarily taken in a prescribed order, although there is a logical sequence to the acquisition of the skills and knowledge concerned. To gain, the award, the candidate must successfully complete all of the following mandatory units: Machine Woodworking: Shaping Machines Machine Woodworking: Sawing Machine Woodworking: Planing, Moulding and Sanding Machine Woodworking: Computer Aided Manufacture (CAM) Machine Woodworking: Jointing Techniques plus two of the following optional units: Machine Woodworking: Profile Grinding Machine Woodworking: Setting Out Machine Woodworking: CNC Machining (Routing) Machine Woodworking: CNC Part Programming (Routing) 8
