TerraNova is a standardized test published by the CTB Corporation. It is administered annually to DoDEA students in grades 3-11.
All TerraNova scores are reported in percentiles - not percentages. A percentile is a measure of comparison that ranks one score against the scores of all other test takers. For example, a 75 percentile score means that 75 percent of all other test takers nationally scored below and 25 percent scored above that score. The national average is always the 50%ile.
