This Sorting Hat Quiz, as stated in the description, was formed using questions similar to those used in the NEO-PI Personality Inventories, measuring the "Big Five" Personality traits (Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism). However, it does not use the same scoring system and House points are totaled rather than traits.
There are four possible results: Gryffindor, Slytherin, Ravenclaw, and Hufflepuff. Since the Sorting Hat also takes into account personal preference, for those of you who would be borderline (like Harry Potter himself), there is a question asking for your preference (accounts for 5-8%). It's enough to bump you borderline folks into a house, but not enough to improperly categorize anyone.
This test contains a total of 125 True/False questions and 1 personal house preference question. At the end, you will see your percentages for each house: a lot of the houses are similar to each other, so the percentages will seem relatively close together (that's why there are a lot of questions!) Have fun, and any feedback is much appreciated!
