Overview

In a sensible demonstration with questions, an unbiased assessor observes the apprentice finishing a process or collection of duties set by the EPAO. The EPAO decides the place it takes place. The evaluation atmosphere should carefully relate to the apprentice’s pure working atmosphere. This permits the apprentice to exhibit the KSBs mapped to this evaluation technique. 

Rationale

This EPA evaluation technique is getting used as a result of:

  • whereas this occupation includes sensible duties greatest assessed by commentary on-the-job, the chance to exhibit the transferable abilities 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 permits all apprentices to have the identical alternative to exhibit 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

Supply

The sensible demonstration with questions should be structured to present the apprentice the chance to exhibit the KSBs mapped to this evaluation technique to the best out there 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 should be as unobtrusive as potential.

The EPAO should give an apprentice not less than 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 process or reply to a query if essential.

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 depend in direction of the full EPA time.

EPAOs should handle invigilation of the apprentice throughout the evaluation, to take care of safety of the EPA, according to their malpractice coverage. This consists of breaks and shifting between areas throughout 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 depend in direction of the evaluation time.

The unbiased assessor should observe the next throughout the sensible evaluation:

a. making ready work space; utilizing well being and security controls

b. use of knowledge and documentation, together with drawings and threat assessments

c. choosing acceptable instruments and work holding gadgets; put together and setup both:

  • typical machine together with instrument setting or,
  • CNC (pc numerical management) machine together with loading and enhancing programmes. Enhancing 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 completely different operations to provide advanced parts with a minimal of three completely different options utilizing one sort of machine that would embrace:

Typical or CNC lathe

  • screw-cutting inner or exterior threads
  • bored holes
  • tapered diameters
  • profile varieties
  • eccentric options
  • grooves or undercuts

Typical 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

Typical 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 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 should be verified by the unbiased assessor. High quality and accuracy requirements should embrace relevant tolerances under:

  • parts to be free from false instrument cuts, burrs and sharp edges
  • common 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 part and have and should 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 customary) 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 tools figuring out and actioning points

The checklist above will not be exhaustive and the EPAO and the employer ought to focus on appropriate machine varieties. Tolerances might be set by the EPAO if the machine will not be specified.

These actions present the apprentice with the chance to exhibit the KSBs mapped to this evaluation technique.

The unbiased assessor should ask questions. The aim of the unbiased assessor’s questions might be to help evaluation within the following themes:

  • work atmosphere
  • instruments and tools
  • planning
  • machine preparation
  • manufacture advanced parts with options

The unbiased assessor’s questions may also check the apprentice’s breadth and depth of underpinning information towards the grading descriptors.

Questions should be requested after the sensible. The overall length of the sensible is 4.5 hours and the time for questioning is included within the total evaluation time. The overall time for the sensible aspect is 4 hours. The time allotted for questioning is half-hour.

The unbiased assessor should ask not less than 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 stored to a minimal.

The unbiased assessor should maintain correct data of the evaluation. They need to file:

  • 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 choice. The sensible evaluation and responses to questions should be assessed holistically by the unbiased assessor when they’re deciding the grade. 

Evaluation location

The sensible demonstration with questions will happen in a simulated atmosphere chosen by the EPAO (for instance the EPAO’s or employer’s premises). The simulated atmosphere should relate to the apprentice’s pure work atmosphere. Gear and assets wanted for the sensible demonstration with questions should be supplied by the EPAO, who can liaise with the employer to offer 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 executed in session with employers of this occupation. The EPAO ought to keep the safety and confidentiality of EPA supplies when consulting employers. The evaluation specification and query financial institution should be reviewed not less than annually to make sure they continue to be fit-for-purpose.  

The evaluation specification should be related to the occupation and exhibit assess the KSBs mapped to this evaluation technique. The EPAO should be sure that questions are refined and developed to a excessive customary. The questions should be unpredictable. A query financial institution of ample dimension will help 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 help the sensible demonstration with questions:

  • unbiased assessor evaluation supplies which embrace:
    • coaching supplies
    • administration supplies
    • moderation and standardisation supplies
    • steerage supplies
    • grading steerage
    • query financial institution
  • EPA steerage for the apprentice and the employer
