This is an exploratory non-experimental research study whose main objective is to compare the teaching styles of a group of thirty teachers of English working in either public or private secondary education in Chile. In order to collect the required data, two instruments were administered to the participants: a teaching style inventory and a personality type index proposed by Grasha. Results indicate that public sector participants show a facilitator teaching style and an extrovert personality type, whereas private sector participants reveal a more authoritative teaching style and an introverted type of personality.
