In a sensible demonstration with questions, an unbiased assessor observes the apprentice finishing a activity or collection of duties set by the EPAO. The EPAO decides the place it takes place. The evaluation setting should intently relate to the apprentice’s pure working setting. This permits the apprentice to show the KSBs mapped to this evaluation technique.
This EPA evaluation technique is getting used as a result of:
- whereas this occupation includes sensible duties finest assessed via remark on-the-job, the chance to show the transferable abilities required could also be restricted in an actual work context resulting from accessibility and scheduling points
- a sensible demonstration has been chosen as this permits all apprentices to have the identical alternative to show their competence in opposition to the KSBs
- questioning permits for the evaluation of the breadth and depth of underpinning data in opposition to the grading descriptors
- it’s a holistic evaluation technique
The sensible demonstration with questions have to be structured to offer the apprentice the chance to show the KSBs mapped to this evaluation technique to the very best obtainable grade.
An unbiased assessor should conduct and assess the sensible demonstration with questions.
The unbiased assessor should solely observe one apprentice at a time to make sure high quality and rigour. They have to be as unobtrusive as doable.
The EPAO should give an apprentice a minimum of 2 weeks discover of the sensible demonstration with questions.
The sensible demonstration with questions should take 4.5 hours.
The unbiased assessor can improve 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 crucial.
The sensible demonstration with questions can’t be break up, aside 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 keep up safety of the EPA, according to their malpractice coverage. This contains breaks and shifting between places in the course of the working day.
The unbiased 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 unbiased 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. deciding on acceptable instruments and work holding gadgets; 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 beneath.
d. performing machining operation; setting and adjusting working parameters; deciding on speeds and feeds; combining a minimal of three completely different operations to supply complicated elements with a minimal of three completely different options utilizing one kind of machine that might embrace:
Typical or CNC lathe
- screw-cutting inside or exterior threads
- bored holes
- tapered diameters
- profile types
- eccentric options
- grooves or undercuts
Typical or CNC Milling machine
- inside pockets or profiles
- inside 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 pictures
- steps or shoulders
- open ended pictures or enclosed pictures and recesses
Typical or CNC floor or cylindrical grinding machine
- inside profiles
- exterior profiles
- stepped diameters
- eccentric diameters
- flat face
- stepped faces
- angled faces
- profiled faces
- parallel faces
- recessed options
e. utilizing gear to measure and test the machined part with a minimal of three options. The manufactured part 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 unbiased assessor. High quality and accuracy requirements should embrace relevant tolerances beneath:
- elements 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 rely on the kind of part 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 commonplace) requirements limits and matches)
- 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 gear figuring out and actioning points
The listing above isn’t exhaustive and the EPAO and the employer ought to talk about appropriate machine sorts. Tolerances shall be set by the EPAO if the machine isn’t specified.
These actions present the apprentice with the chance to show the KSBs mapped to this evaluation technique.
The unbiased assessor should ask questions. The aim of the unbiased assessor’s questions shall be to assist evaluation within the following themes:
- work setting
- instruments and gear
- machine preparation
- manufacture complicated elements with options
The unbiased assessor’s questions will even check the apprentice’s breadth and depth of underpinning data in opposition to the grading descriptors.
Questions have to be requested after the sensible. The full length of the sensible is 4.5 hours and the time for questioning is included within the total evaluation time. The full time for the sensible aspect is 4 hours. The time allotted for questioning is half-hour.
The unbiased assessor should ask a minimum of 5 questions. The unbiased 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 unbiased 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 needs to be saved to a minimal.
The unbiased assessor should maintain 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 unbiased assessor should make the grading determination. The sensible evaluation and responses to questions have to be assessed holistically by the unbiased 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. Gear and sources wanted for the sensible demonstration with questions have to be offered 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 improvement
The EPAO should develop a purpose-built evaluation specification and query financial institution. It’s endorsed that is performed 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 a minimum of annually to make sure they continue to be fit-for-purpose.
The evaluation specification have to be related to the occupation and show the right way to assess the KSBs mapped to this evaluation technique. The EPAO should be certain that questions are refined and developed to a excessive commonplace. The questions have to be unpredictable. A query financial institution of enough dimension will assist this.
The EPAO should be certain that the apprentice has a special 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:
- unbiased 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
