What is the purpose of the rating system?Movie ratings provide the audience with advance information about the content of films to help them determine what movies are appropriate for their young children and at what age.  Ratings are assigned by a Board of parents who consider factors such as violence, sex, language, drug use and other adult activities and assign a rating they believe the majority of American parents would give a film.Do the ratings indicate if a movie is good or bad?No.  Audiences and film critics make these determinations.  The ratings are not intended to approve, disapprove or censor any film. Rather, ratings imply offer guidance to parents as to the level of content in a film.

A test screening is a preview screening of a movie or television show before its general release in order to gauge audience reaction. Preview audiences are selected from a cross-section of the population, and are usually asked to complete a questionnaire or provide feedback in some form. Harold Lloyd is credited with inventing the concept, having used it as early as 1928. Test screenings have been recommended even for starting filmmakers "even if a film festival is fast approaching”.

Focus groups are a research method used to gather feedback and opinions from customers. Each person in the group is encouraged to participate in a discussion which is pre-planned by a researcher and is guided by a facilitator. Focus groups are typically used to gauge opinion and gather information from users about products, services, and features before they have been developed.

Critic (or "press") screenings are held for national and major market critics well in advance of print and television production-cycle deadlines, and are usually by invitation only. This step may be omitted if a studio anticipates negative critical reviews, or if a film is still being edited until immediately before release.

When conducting my own audience research when I created my own film trailer I had my own focus group full of yr. 12/13 student and asked them to fill in a questionnaire. This aided me when conducting my audience research as it helped target my specific audience and also make some editing changes.

When I resaved my audience feedback I reaves some mixed result but I look the negatives as constructive criticism and changed my trailer for the better.
