How is the STB Test Scored?
STB scores are scaled, which are based upon the number of questions that the individual is able to answer correctly. The student’s raw score, or the number of questions answered correctly, is converted to a common scale. This process allows the admissions committee to establish a score comparison among the students taking the exam. The STB is a normed test which means that the individual test taker is compared to a group of test takers. This provides insight into whether the test taker performed increasingly better or worse than the other members in the sample pool. In the case of the STB, the comparison population consists of other talent search peers in the 5th and 6th or 7th and 8th grades.
Raw Score determines percentage.
Scaled Score determines percentile.
Out-of-Level Testing as conducted by CTY
The CTY traditionally assesses a student’s score by comparing students to an older population of individuals. For example, Grade 2 students are compared to 4th graders, Grade 3 to Grade 5, Grade 4 to Grade 6, Grade 5 to Grade 8, Grade 6 to Grade 9, Grade 7 to Grade 12, and Grade 8 to Grade 12.
