    A.
    All controls (switches, knobs, etc.) clearly and neatly labeled
    B.

    70 %

    (Must meet or exceed these criteria in addition to all criteria for 65%)

    A.
    All wire connections sound (solder joints, wire-wrap, terminal strips, and lugs are all connected properly)
    B.
    No use of glue where a fastener would be more appropriate
    C.
    Deadline met for submission of fully-functional project (Date/Time = / ) - supersedes 75.C if final project submitted by that (earlier) deadline
    65 %

    (Must meet or exceed these criteria in addition to all criteria for 60%)

    A.
    Project fully functional
    B.
    All components securely fastened so nothing is “loose” inside the enclosure

    Schematic diagram of circuit
    60 %

    (Must meet or exceed these criteria in addition to being safe and legal)

    A.
    Project minimally functional, with all components located inside an enclosure (if applicable)
    B.
    Passes final safety inspection (proper case grounding, line power fusing, power cords strain-relieved)
    0 % (If any

    of the following conditions are true)

    A.
    Fails final safety inspection (improper grounding, fusing, and/or power cord strain relieving)
    B.
    Intended project function poses a safety hazard
    C.
    Project function violates any law, ordinance, or school policy
