What reading level is the Personal Analysis questionnaire is designed for?
Assuming a person has had a normal, proper schooling, he/she should be able to respond to the questionnaire at the age of 15 (it’s been done successfully at the age of nine). However, a more important aspect is the formation of one’s personality and self-identity. This definitely pushes the age up to around 18. Therefore, it is not recommended that the questionnaire be used for individuals younger than 18.
