In a sensible demonstration with questions, an impartial assessor observes the apprentice finishing a activity or sequence of duties set by the EPAO. The EPAO decides the place it takes place. The evaluation setting should carefully relate to the apprentice’s pure working setting. This permits the apprentice to reveal the KSBs mapped to this evaluation technique.
This EPA evaluation technique is getting used as a result of:
- whereas this occupation entails sensible duties greatest assessed by statement on-the-job, the chance to reveal the transferable expertise required could also be restricted in an actual work context on account of accessibility and scheduling points
- a sensible demonstration has been chosen as this allows all apprentices to have the identical alternative to reveal their competence towards the KSBs
- questioning permits for the evaluation of the breadth and depth of underpinning information towards the grading descriptors
- it’s a holistic evaluation technique
The sensible demonstration with questions have to be structured to present the apprentice the chance to reveal the KSBs mapped to this evaluation technique to the very best obtainable grade.
An impartial assessor should conduct and assess the sensible demonstration with questions.
The impartial assessor should solely observe one apprentice at a time to make sure high quality and rigour. They have to be as unobtrusive as potential.
The EPAO should give an apprentice at the least 2 weeks discover of the sensible demonstration with questions.
The sensible demonstration with questions should take 4.5 hours.
The impartial assessor can enhance the time of the sensible demonstration with questions by as much as 10%. This time is to permit the apprentice to finish a activity or reply to a query if obligatory.
The sensible demonstration with questions can’t be break up, apart from for consolation breaks or to permit apprentices to maneuver from one location to a different. The place breaks happen, they won’t rely in the direction of the entire EPA time.
EPAOs should handle invigilation of the apprentice in the course of the evaluation, to take care of safety of the EPA, in keeping with their malpractice coverage. This contains breaks and shifting between places in the course of the working day.
The impartial assessor should clarify to the apprentice the format and timescales of the sensible demonstration with questions earlier than it begins. This doesn’t rely in the direction of the evaluation time.
The impartial assessor should observe the next in the course of the sensible evaluation:
a. making ready work space; utilizing well being and security controls
b. use of data and documentation, together with drawings and danger assessments
c. choosing applicable instruments and work holding units; put together and setup both:
- standard machine together with device setting or,
- CNC (pc numerical management) machine together with loading and enhancing programmes. Modifying programmes should embrace including substantive options to the prevailing programme as described within the operations listed under.
d. performing machining operation; setting and adjusting working parameters; choosing speeds and feeds; combining a minimal of three totally different operations to supply complicated parts with a minimal of three totally different options utilizing one kind of machine that might embrace:
Standard or CNC lathe
- screw-cutting inner or exterior threads
- bored holes
- tapered diameters
- profile types
- eccentric options
- grooves or undercuts
Standard or CNC Milling machine
- inner pockets or profiles
- inner round or curved profiles
- exterior curved profiles
- holes or options linearly pitched
- holes or options spaced on a PCD (pitched circle diameter)
- bored holes
- treadmilling or tapping
- keyway or tee photographs
- steps or shoulders
- open ended photographs or enclosed photographs and recesses
Standard or CNC floor or cylindrical grinding machine
- inner profiles
- exterior profiles
- stepped diameters
- eccentric diameters
- flat face
- stepped faces
- angled faces
- profiled faces
- parallel faces
- recessed options
e. utilizing tools to measure and examine the machined element with a minimal of three options. The manufactured element with a minimal of three options should conform to all high quality and accuracy requirements relevant to the machine and operations being carried out and have to be verified by the impartial assessor. High quality and accuracy requirements should embrace relevant tolerances under:
- parts to be free from false device cuts, burrs and sharp edges
- normal dimension tolerance. As much as plus or minus 0.25mm or plus or minus 0.010 inch
- a number of particular dimensional tolerances. Particular dimensional tolerances depend upon the kind of element and have and have to be agreed with the EPAO prematurely. As much as plus or minus 0.05mm or plus or minus 0.002 inch or BS EN 20286 or BS 1916 Grade 7 (BS (british normal) requirements limits and suits)
- reamed and bored holes inside H8
- screw threads BS medium match
- geometric tolerances of 0.1mm or 0.004 inch
- angles and tapers inside plus or minus 0.5 diploma
- in grinding operations, flatness and squareness inside 0.012mm per 25mm or 0.0005 inch per inch
f. sustaining a protected machine and work space all through the machining course of; checking the situation of instruments and tools figuring out and actioning points
The checklist above just isn’t exhaustive and the EPAO and the employer ought to talk about appropriate machine sorts. Tolerances can be set by the EPAO if the machine just isn’t specified.
These actions present the apprentice with the chance to reveal the KSBs mapped to this evaluation technique.
The impartial assessor should ask questions. The aim of the impartial assessor’s questions can be to assist evaluation within the following themes:
- work setting
- instruments and tools
- machine preparation
- manufacture complicated parts with options
The impartial assessor’s questions may also take a look at the apprentice’s breadth and depth of underpinning information towards the grading descriptors.
Questions have to be requested after the sensible. The whole period of the sensible is 4.5 hours and the time for questioning is included within the general evaluation time. The whole time for the sensible ingredient is 4 hours. The time allotted for questioning is half-hour.
The impartial assessor should ask at the least 5 questions. The impartial assessor should use the questions from their EPAO’s query financial institution or create their very own questions in-line with the EPAO’s coaching.
The impartial assessor can ask follow-up inquiries to make clear solutions given by the apprentice. These questions are along with the above set variety of questions for the sensible demonstration with questions and must be stored to a minimal.
The impartial assessor should hold correct information of the evaluation. They have to document:
- the KSBs noticed
- the apprentice’s solutions to questions
- KSBs demonstrated in solutions to questions
- the grade achieved
The impartial assessor should make the grading choice. The sensible evaluation and responses to questions have to be assessed holistically by the impartial assessor when they’re deciding the grade.
The sensible demonstration with questions will happen in a simulated setting chosen by the EPAO (for instance the EPAO’s or employer’s premises). The simulated setting should relate to the apprentice’s pure work setting. Tools and assets wanted for the sensible demonstration with questions have to be supplied by the EPAO, who can liaise with the employer to supply these.
Questioning that happens after the sensible demonstration with questions ought to happen in a quiet room, free from distractions and affect.
Query and useful resource growth
The EPAO should develop a purpose-built evaluation specification and query financial institution. It’s endorsed that is completed in session with employers of this occupation. The EPAO ought to preserve the safety and confidentiality of EPA supplies when consulting employers. The evaluation specification and query financial institution have to be reviewed at the least annually to make sure they continue to be fit-for-purpose.
The evaluation specification have to be related to the occupation and reveal methods to assess the KSBs mapped to this evaluation technique. The EPAO should be sure that questions are refined and developed to a excessive normal. The questions have to be unpredictable. A query financial institution of enough dimension will assist this.
The EPAO should be sure that the apprentice has a distinct set of questions within the case of re-sits or re-takes.
The EPAO should produce the next supplies to assist the sensible demonstration with questions:
- impartial assessor evaluation supplies which embrace:
- coaching supplies
- administration supplies
- moderation and standardisation supplies
- steering supplies
- grading steering
- query financial institution
- EPA steering for the apprentice and the employer
