What criteria do IPMS judges look at?

IPMS judges typically assess construction quality (seam lines, gaps, alignment), surface finish (smoothness, absence of defects), painting (coverage, blending, weathering), detailing (added detail, accuracy), and overall presentation. Criteria vary by chapter and competition.

What score is needed to win a medal?

In this calculator, 90%+ earns Gold, 80-89% Silver, 70-79% Bronze, and 60-69% Commended. Real competitions vary, but these thresholds reflect typical UK model show standards.

Why are some criteria weighted more heavily?

Construction and finish are weighted higher because they form the foundation of a good model. A perfectly painted model with poor construction will score lower than a well-constructed model with good (not perfect) paint. Most judges agree that you cannot paint your way out of poor construction.

How can I improve my competition scores?

Focus on eliminating basic errors first: fill all seams, remove mould lines, ensure correct alignment. Then work on paint consistency and thin coats. Weathering and detailing are the final steps. Join a local IPMS club for constructive feedback.
