Professional Commentary

Students are asked to determine which value could be the square of a number plotted on the number line. This multiple-choice question is a sample item used in the 2008 Ohio Graduation Test (see Overview of Ohio's Assessment System). The URL link (above) takes the user directly to the OGT test item (PDF), with access to performance data, complexity level of the item, and discussion of incorrect responses. This OGT item is also available in Microsoft® Word. The Ohio Department of Education Instructional Management System website allows visitors to search for test items by subject and grade band and build a printable database of questions using the Add to Your Backpack function.
