Levels are not simple, discrete categories. Levels are not simple, discrete categories. There is a continuum of performance There is a continuum of performance within each level. Students who are just within each level. Students who are just barely proficient are somewhat less likely barely proficient are somewhat less likely to answer a given question correctly than to answer a given question correctly than students who have almost reached the students who have almost reached the advanced level. Nonetheless, averaging advanced level. Nonetheless, averaging across the range covered by each across the range covered by each achievement level provides a clear and achievement level provides a clear and reasonable summary of results for reasonable summary of results for students at that level. students at that level.

The CST sample questions, at The CST sample questions, at www.starsamplequestions.org are tied are tied to a particular proficiency. Items were selected to illustrate what a to a particular proficiency. Items were selected to illustrate what a majority of students at a performance level could answer correctly.majority of students at a performance level could answer correctly.
For example, if the question is a Proficient Sample, that indicates that For example, if the question is a Proficient Sample, that indicates that most of the students who achieved an overall “Proficient” score most of the students who achieved an overall “Proficient” score were able to answer that particular question correctly. Less than half were able to answer that particular question correctly. Less than half of the students with an overall “Basic” score could not answer it of the students with an overall “Basic” score could not answer it correctly. In other words, that question typifies what a “Proficient” correctly. In other words, that question typifies what a “Proficient” student knows and can do. student knows and can do.

In addition to Proficient, in-depth inferences or applications that go beyond what was taught. For example, the student may:
Score3
(Proficient)
The student will:
The student exhibits no major errors or gaps in the learning goal (simple and complex processes).
Score2
(Basic)
The student will:
The student exhibits no major errors or gaps in the simpler details and processes.
Score1
(Below Basic)With help, a partial understanding of the learning goal.

An Advanced student will be able to answer:What is the prime factorization of 36?What is the prime factorization of 72?
A Proficient student will be able to answer:What is the prime factorization of 45?What is the prime factorization of 12?
A Basic student will be able to answer:What is the prime factorization of 15?5³ = (answer: 5 x 5 x 5)
