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 percentile score of 75 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 percentile score of 50.
