Demonstrate Mastery: Substrate Preparation Evaluation
Demonstrate Mastery
This is your mastery demonstration for Month 6. Your journeyman will observe you prepare a substrate from start to finish and score your performance. No coaching during the demonstration — show what you know.
This Month’s Wrap-Up
Month 6: Substrate Preparation for Sign Components
Over the past four weeks you researched substrate materials and their preparation requirements, studied the methods and safety practices for cleaning, abrading, and priming different sign substrates, applied those skills on a real job task, and reflected on your performance. This final evaluation confirms you can prepare substrates correctly and independently for the three primary end uses: vinyl application, paint application, and illuminated component mounting.
Competency — Core
- Identify substrate material and select the correct preparation method for the specified end use
- Execute substrate preparation steps in the correct sequence using proper technique and PPE
- Produce a finished substrate that meets shop quality standards and is ready for the next production operation
Demonstrate & Document
Action:
Your journeyman or supervisor will observe and evaluate your ability to demonstrate this competency in your normal work environment and score your performance using the CraftED Competency Evaluation Form.
What you will demonstrate:
- Assess the assigned substrate: identify the material type, the intended end use, and any surface conditions that require attention before prep begins
- Select and gather the correct preparation materials and PPE for the substrate type and end use without prompting
- Execute all preparation steps in the correct sequence — cleaning, abrading, priming, or sealing as required — using proper technique throughout
- Present the completed substrate to your journeyman, explain the steps you performed and why, and confirm it is ready for the next operation
SECTION 3 — ASSIGNMENT
- Schedule the Demonstration — Coordinate with your journeyman to schedule your mastery demonstration during regular work hours this week. The demonstration should take place on an actual substrate from current shop work — not a practice piece. — Confirm with your journeyman which substrate material and end use will be assigned so the evaluation reflects real production conditions.
- Conduct the Demonstration — Perform the full substrate preparation process from initial assessment through completed prep without prompting. Your journeyman observes but does not coach during the demonstration. — Narrate your decisions as you work — explain what you’re doing and why at each step. This shows your journeyman that your actions are deliberate, not guesswork.
- Journeyman Debrief and Scoring — After the demonstration, your journeyman will give you verbal feedback on your performance covering each rubric criterion. Listen and take notes — this feedback applies directly to your next substrate prep task. — Your journeyman completes the scoring rubric and records the result. A score of 3 (Meets) or higher on all criteria confirms mastery of this competency.
- Submit the Completed Rubric — Your journeyman uploads the completed rubric through the course portal or submits it to the program administrator according to CN Signs’ documentation process. — If any criterion scores below 3, your journeyman will identify a specific remediation task. Complete that task and request a focused re-evaluation on the criterion that did not meet the standard.
Your submission for this section:
Journeyman completes and submits the mastery rubric through the course portal. Apprentice does not self-score this evaluation. Both parties should retain a copy of the completed rubric for the apprenticeship record.
Section 4: Evaluation Rubric
| Criterion | Exceeds (4) | Meets (3) | Approaches (2) | Needs Support (1) |
|---|---|---|---|---|
| Substrate and Surface Condition Assessment | Independently identifies material type, end use, and all relevant surface conditions before touching the substrate. Articulates findings clearly without prompting. | Correctly identifies material type and end use. Notes primary surface conditions that affect prep approach. | Identifies material type but misses one surface condition or end use consideration. Requires one prompt to complete assessment. | Unable to identify material or end use without journeyman guidance. Assessment is incomplete or incorrect. |
| Preparation Method and Material Selection | Selects the exact correct preparation method, tools, and materials for the substrate and end use without any prompting. Explains the rationale for each item selected. | Selects the correct preparation method and gathers appropriate materials with minimal prompting. | Selects a mostly correct method but gathers an incorrect or missing material. Corrects when prompted before starting. | Selects an incorrect preparation method or critical material. Requires journeyman direction to correct before work can begin. |
| Preparation Step Sequence and Technique | Executes all steps in correct sequence with professional technique. No steps skipped. Surface is consistent and ready for next operation at the first attempt. | Executes steps in correct sequence with acceptable technique. Surface is ready for next operation. Minor coaching accepted after demonstration. | Completes most steps correctly but sequence is partially out of order or technique is inconsistent. Surface may require additional work. | Steps are out of sequence, incomplete, or technique is incorrect. Surface is not ready for next operation without rework. |
| PPE and Safety Compliance | Applies all required PPE and solvent handling practices throughout the full demonstration without any prompting. Maintains a clean, organized work area. | Applies required PPE and safety practices throughout. No more than one minor prompt needed from journeyman. | Applies most safety practices but misses one PPE or solvent handling requirement. Corrects immediately when prompted. | Safety practices are absent or inconsistent. Journeyman must intervene to prevent an unsafe condition during the demonstration. |
| Communication and Explanation of Work | Narrates each step and decision clearly throughout the demonstration. Explains why each step is performed and what would happen if it were skipped. | Explains major steps and key decisions during the demonstration. Communication is clear and accurate. | Provides some explanation but omits reasoning for one or more steps. Responds correctly when journeyman asks follow-up questions. | Unable to explain the steps being performed or why they are required. Communication does not support demonstration of understanding. |
