Commoners IMC are handled somewhat differently than in the DMG. They can gain levels fairly easily along with feats, skills and ability score bonuses but no combat ability. That is, no BAB bonuses, no additional HPs beyond 1st level, no Saving Throw increases. A commoner can gain toughness in order to gain extra HPs or multiclass into a Warrior (again, slightly revamped for my game) or other true fighting class.
With that in mind, commoners are ranked thusly:
Novice: Com 1
Trained: Com 2-4
Experienced: Com 5-7
Expert: Com 8-10
Master: Com 11-15
World Renoun: 16+
In some of the more dangerous regions, there may be statutory combat training for everyone so everyone has at least 1 level in Warrior in addition to their Commoner levels.
