BCPE CPE cheat sheet

Fitts's law: movement time MT = a + b·log2(2D/W), where D is target distance and W is target width; larger or closer targets reduce MT.

Hick-Hyman law: choice reaction time rises linearly with log2(n+1) bits of stimulus uncertainty; each doubling of equally likely alternatives adds roughly a constant increment.

NIOSH lifting equation: Recommended Weight Limit RWL = LC × HM × VM × DM × AM × FM × CM; Lifting Index LI = Load Weight ÷ RWL, with LI > 1.0 flagging increased risk.

Stevens' power law: perceived magnitude S = k·I^n; n < 1 indicates compressive response (e.g., brightness), n > 1 expansive (e.g., electric shock).

Weber fraction: just-noticeable difference is a constant proportion of the reference stimulus, ΔI/I = k; smaller k means finer discrimination.

Anthropometric design rules: design for the extremes (clearance = 95th percentile, reach = 5th percentile) and adjustability for the central range (5th-95th).

Signal detection theory: d' = z(hit rate) − z(false-alarm rate) measures sensitivity; criterion c = −0.5[z(H) + z(FA)] measures response bias, independent of sensitivity.

Mental workload indices: NASA-TLX combines six weighted subscales; secondary-task decrement and physiological measures (pupillometry, heart-rate variability) provide converging estimates.

Cognitive load types: intrinsic load from task complexity, extraneous load from poor design, germane load from schema construction; design aims to cut extraneous load.

BCPE certification requires a combination of education and professional ergonomics experience; the exact credit thresholds are set by the certifying board and should be verified against current official criteria.

Degree relevance is evaluated by transcript content: coursework in ergonomics, biomechanics, physiology, psychology, or safety determines how education credits are counted.

Professional experience must be documented with dates, employer, job title, and descriptions showing application of human factors/ergonomics methods.

Work experience is typically credited only when it is performed at a professional level and is substantially ergonomics-related; unrelated or purely clerical duties are excluded.

References or supervisor verification are commonly required to substantiate claimed experience; unverifiable claims may be disallowed.

Recertification typically requires continuing education units earned through approved ergonomics, safety, or human-factors coursework and conference attendance.

Ethics and professional-conduct standards are part of the certification framework; violations can lead to sanctions or revocation independent of exam scores.

Applications are reviewed against published eligibility rules; candidates below thresholds may qualify through additional education or additional supervised experience.
