"Your character's Intelligence modifier affects the number of skill points he or she gets at each level (see Table 1-1: Ability Modifiers and Bonus Spells, page 8). This rule represents an intelligent character's ability to learn faster over time. Use your character's current Intelligence score, including all permanent changes (such as inherent bonuses, ability drains, or an Intelligence increase gained ar step 4, above) but not any temporary changes (such as ability damage, or enhancement bonuses gained from spells or magic items, such as a headband of intellect), to determine the number of skill points you gain."
