2014 ISAT Grade 7 Sample Book4

2014 ISAT Grade 7 Sample BookIntroductionThis sample book contains sample ISAT science items classified with an assessment objective fromthe Illinois Assessment Frameworks. These 2014 samples are meant to give educators and students ageneral sense of how items are formatted for ISAT. All 2014 ISAT test booklets will be printed incolor. This sample book does not cover the entire content of what may be assessed. Please refer tothe Illinois Assessment Frameworks for complete descriptions of the content to be assessed at eachgrade level and subject area. The Illinois Assessment Frameworks are available online atwww.isbe.net/assessment/IAFindex.htm. The Student Assessment Web site contains additionalinformation about state testing (www.isbe.net/assessment).5

2014 ISAT Grade 7 Sample BookStructure of the Grade 7 Science ISATISAT Science testing in spring 2014 will consist of 82 criterion-referenced items written by Illinoiseducators.Item FormatsAll 82 items will be in multiple-choice format. All items are aligned to the Illinois Science AssessmentFramework, which defines the elements of the Illinois Learning Standards that are suitable for statetesting.Science SessionsAll standard time administration test sessions are a minimum of 45 minutes in length. Any studentwho is still actively engaged in testing when the 45 minutes have elapsed will be allowed up to anadditional 10 minutes to complete that test session. More details about how to administer this extratime will appear in the ISAT Test Administration Manual. This policy does not affect students whoalready receive extended time as determined by their IEP.Science ISAT Grade 7Session 145 minutes41 multiple-choice itemsSession 245 minutes41 multiple-choice items(Some items will be pilot items.)Cumulative KnowledgeISAT tests students on the knowledge and skills that they should have acquired by grade 4 andgrade 7. Proper curriculum alignment can establish which assessment objectives are covered at eachgrade level so that by the spring of any given year, all objectives have been presented. It is not thesole responsibility of a 4th grade teacher or a 7th grade teacher to teach all of the assessmentobjectives contained within the framework.The grade 4 ISAT will assess the grade 4 assessment objectives. The grade 7 ISAT will assess thegrade 7 assessment objectives but may also include the assessment objectives from grade 4. Thesample items within this booklet provide the reader with an opportunity to see the ISAT format andhow the items align to the assessment framework.7
