Culture and religion
The child will often adopt the culture or religion of his tutor, hence the importance of guardian choice. This happens more often if the guardian is:
However, these events will not happen if the tutor is not of the same culture or religion as their employer (landed nobles are their own employers).
Upon turning 16 and becoming an adult, the character will receive an Education trait.
For each attribute there are four levels, ranging from mediocre to great. The highest level improves that attribute by a large amount, and is thus highly desirable. What education trait a character gets is semi-random, but usually in the same area as their guardian, and often at the same level as well.
The determination of the trait a child receives is hardcoded and not directly visible. Experimentation has shown that it only depends on the education trait of the guardian, which is therefore generally considered a very important factor when choosing a guardian:
- guardian skills, personality traits or opinion have no influence
- the length of time the guardian has educated the child has no impact
- education traits from all attributes behave in the same way.
The probability of getting:
- the same rank trait as the guardian is roughly 50%
- a rank one step away from the guardians rank is roughly 15-30%
- a rank two steps away from the guardians rank is roughly 5%-10%
- a rank three steps away from the guardians rank is roughly 8%
Some more detailed results from experiments:
Personality traits are also gained during tutoring and help define the character. AI guardians will generally encourage their wards to have traits similar to their own, while players acting as guardians are mostly free to guide wards in any chosen direction.
Some traits that affect AI guardians are:
- very good: , , and guardians make good choices in many events.
- good: guardians make good choices, and guardians stay out of the way when the child is doing well naturally.
- mediocre: guardians are good at making children Zealous, but leave almost everything else up to chance.
- bad: , , , , and

Effects on guardians
Many events have options with effects on guardians:
- Lose or , by approving of a child gaining the opposite trait
- Gain 5 piety by choosing religious options such as praying (requires not being )
- Lose 5 prestige by encouraging a child to have certain traits opposite from your own
Many events allow skilled guardians to improve ward stats, but a handful allow skilled guardians to improve their own stats:
- When a child naturally gains or , the guardian can gain 1 diplomacy if already 10+
- When a child naturally gains , the guardian can gain 1 intrigue if already 10+
- Each event can only fire if the child does not have the trait or its opposite
- Each event can only fire if the child has fewer than 5 personality traits
- Each event is 10x more likely to fire for children, and 2x more likely to fire for quick or weak children.
Choose guardians based on the stats and traits you want each character to have:
- Your heir should be a likable ruler with strong stats.
- The same applies to your heir's heir, or anyone you might choose as an heir.
- Vassals should be , share your culture, and share positive personality traits with your heir.
- Claimants on your titles should be managed carefully, lest they become adventurers or gain faction support.
- Dynastic claimants on foreign realms should be encouraged to become adventurers, so you can join their war and gain an ally.
- Future cardinals and antipopes should be virtuous, pious, and generally likable.
- Future council members should be strong in their primary attribute.
- Future spymasters should also have high ai_honor so they don't help murder your kids, but this tends to conflict with having high intrigue skill...
Educate heir yourself: you have much better control over a child's personality this way than by choosing a guardian. Once the child has 5 personality traits, you can safely send them to another tutor for better stats or education trait. (this is no longer a guarantee, there have been reports of a 6th, or even 7th trait before the age of 16)
Always have two wards: choices in the events can help your character, especially if you don't care about the child's well-being.
Look for guardians with Tier 4 education traits: having such a tutor in the last year gives the child a good chance to pick up the same education, for +9 in one stat and +2 in two others.
If you pick a guardian outside your own court, be careful with guardians of other religions/cultures, unless you actually want to switch religion/culture. If both the guardian and the owner of the court the guardian is in (the same person if the guardian themself is landed) is of a different culture/religion, your child may switch. Note that if you are a child, you can choose to avoid the culture- and religion-changing events, so you can have a different-culture guardian without danger of being unwillingly converted.
Choose an appropriate education for your heir, depending on circumstances:
