No, just implement your clean_YOURFIELDNAME method of the form.
class Person(Form):
... (fields declaration follow)
def clean_student_seniority(self):
if (self.clean_data.get("person_type") == 1) and
(self.clean_data.get("student_seniority") == None):
raise ValidationError(u"Students must have a seniority
defined")
return self.clean_data["student_seniority"]
Then in your view you check if form.is_valid()
