Personality Quiz - For older grades. This quiz has a several paragraph explanation before the questions and gives a very detailed report after schools takes it. You could spend one advisory reading and discussing the intro and the next actually taking the test and reading the results. Would recommend teachers take it before students so you know what the results will look like. One question mentioned figurative language- review that with students.
