2007 ISAT Grade 5 Sample Book
Structure of the Grade 5 Mathematics ISAT
ISAT Mathematics testing in spring 2007 will consist of 30 norm-referenced items, as well as 45 criterion-
referenced items, some of which will be used for developmental purposes. Th e 30 norm-referenced items are
an abbreviated form of the Stanford 10 Mathematics Problem Solving assessment, developed by Harcourt, Inc.
Th e 45 criterion-referenced items are all written by Illinois educators and pilot tested with Illinois students.
Item Formats
All 75 items are aligned to the Illinois Mathematics Assessment Framework, which defi nes the elements of the
Illinois Learning Standards that are suitable for state testing.
Multiple-choice items require students to read, refl ect, pute and then to select the alternative that
best expresses what they believe the answer to be. Th is format is appropriate for quickly determining whether
students have achieved certain knowledge and skills. Well-designed multiple-choice items can measure
student knowledge and understanding, as well as students’ selection and application of problem-solving
strategies. A carefully constructed multiple-choice item can assess any of the levels of mathematical
complexity from simple procedures to sophisticated concepts. Th ey can be designed to reach beyond the
ability of students to “plug-in” alternatives or eliminate choices to determine a correct answer. Such items are
limited in the extent to which they can provide evidence of the depth of students’ thinking.
Short-response items pose similar questions as multiple-choice items and provide a reliable and valid basis
for extrapolating about students’ approaches to problems. Th ese items reduce the concern about guessing
that panies multiple-choice items. Th e short-response items are scored with a rubric and count as
5% of the scale score
