ICCF Title Norm Requirements

The following norm table is based on the ICCF rating system, which is governed by the following general principles;

  • The ICCF Rating system is a numerical system in which percentage scores are converted to rating differences and conversely, rating differences are convertible to scoring probabilities.
  • The basis of the system is the normal probability function of statistical probability theory.

The detailed conversion tables and working formulae can be found in the minutes from the 2000 ICCF Congress.
