The purpose of these practice test materials is to orient teachers and
students to the types of questions on paper-based FSA tests. By using these
materials, students will become familiar with the types of items and response
formats they may see on a paper-based test. The practice questions and
answers are not intended to demonstrate the length of the actual test, nor
should student responses be used as an indicator of student performance on
the actual test. The practice test is not intended to guide classroom
instruction.
