**The number of ICON Specialisations is equal to 1 more than the number of CODA Specialisations. Professional and Species Abilities correspond to various ICON Skills and/or Traits.

Assigning equivalents to skills is largely a matter of GM taste. Systems which are "skills light," such as Traveller, should have the skills broken down into a number of related Star Trek skills.
