"The New Jersey Assessment of Skills and Knowledge For Grade 4 Technical Report Dated May 2003 created and made available by the New Jersey Department of Education is significant to all the parents students and private tutors at all of the three Math Genie abacus math for kids schools in New Jersey in the United States of America, continues on to state the following, quote “The term base form is used to describe the test form on which the raw-to-scale score conversion was originally specified. Standards were set on the base form of the Mathematics Elementary School Proficiency Assessment (ESPA) in 1999. Standards were set on the base form of the Language Arts Literacy ESPA in 2001. Through equating and
scaling procedures, the standards established on the base forms have been carried forward so that the amount of ability needed to score in Proficient and Advanced Proficient performance levels has remained the same each year despite small changes in the difficulty of the test forms".
"For more information on the standards-setting studies for the ESPA, please see the document Standard-Summary Procedures for New Jersey Statewide Assessments.Table 5.1.1 shows the final cut scores that were approved by the State Board of Education. In addition, the table shows the percentage of grade 4 students. Part 6: Item-Level Statistics. 6.1 Classical Item Statistics. For each administration, classical item analyses are completed prior to item calibration, scaling and equating. These statistics are calculated again once all of the data are available. These analyses involve computing, for every item in each form, a set of statistics based on classical test theory. Each statistic is designed to provide some key information about the quality of each item from an empirical perspective".
"The statistics estimated for the NJ ASK are described below. Classical item difficulty P-Value: This statistic indicates the percent of examinees in the sample that answered the item correctly. Desired p-values generally fall within the range of 0.30 to 0.95. Item discrimination r-biserial)1: This statistic is measured by the polyserial correlation between the item score and the test criterion score and describes the relationship between performance on the specific item and performance on the entire form. The higher the value, the better the task of separating the examinees. Items with negative correlations can indicate serious problems with the item content (e.g., multiple correct answers or unusually complex content), or can indicate that students have not been taught the content” end quote".
