1 Quarterly Science Benchmark Assessment (QSBA) Physical Science Quarter 1 Miami-Dade County Public Schools Office of Academics and Transformation

2 INTRODUCTION The Physical Science Quarterly Science Benchmark Assessments (QSBA) were created with the objective of assessing student performance in order to improve the quality of student learning and enhance instructional practices by using data to make curricular decisions. The Physical Science QSBAs are designed to be administered at the start of the school year, after each nine-week period (quarter) of instruction, and at the end of the school year, focusing its questions on the scientific content delineated by the Florida Department of Education (FLDOE) Next Generation Sunshine State Standards (NGSSS) and the specific benchmarks outlined by the Physical Science course description. The Division of Mathematics, Science, and Advanced Academic Programs highly recommends the administration of the QSBAs to be concurrent with the administration of Baseline Assessments, Fall Interim Assessments, and Winter Interim Assessments. The Pre-Test Assessment encompasses all the main concepts and ideas of the Physical Science course, while each Quarterly Assessment addresses the main benchmarks of each quarter specific to the Topics found in the Physical Science District Pacing Guide. The NGSSS benchmarks pertinent to each course description have been grouped according to content and placement within the District Pacing Guides in order to facilitate the analysis of each assessment. Teachers are encouraged to debrief the results of each of the QSBAs with students and use individual test results to focus on the benchmark(s) on which a student needs further instruction. This review will assist teachers in targeting their instruction. Teachers must use the Thinkgate Technology Platform ( to print answer sheets, scan, score, and produce reports. This process will enable teachers to obtain student data in order to identify strengths and weaknesses and allow teachers to target instruction and monitor progress. Additional information regarding the use of Thinkgate can be found in the Interim Assessment section of the department of Assessment, Research, and Data Analysis ( This document was created by the from District-developed questions and may include questions adapted from previously released tests with permission from the Massachusetts Department of Elementary and Secondary Education and the Pennsylvania Department of Education This document cannot be reproduced without express written permission from Miami-Dade County Public Schools.
