"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 2003 Mathematics test used both internal and external anchor items. Internal anchor items are common items that are embedded in the operational set of items (i.e., they count toward a student’s operational score). In 2003, 23 items from 2001 and 2002 forms were used to link back to 1999. Eleven anchor items were embedded
in the new form and 12 were located in external variable sections (Forms A and B). One item was flagged by NJDOE as “Do Not Score".
"As a result, scores on the 2003 NJ ASK grade 4 Mathematics test ranged from 0-42. Based on the performance on the anchor items, the 2003 students appear to be about the same in ability as the 2002 students and the 2003 form was similar in difficulty to the 2002 form. The recommended raw-score (and scale-score) cut points for the 2003 Mathematics NJ ASK based on the equating results were 22.0 (200) and 33.0 (250) for Proficient and Advanced Proficient categories, respectively. Details about the methods and results are described in the 2003 NJ ASK Mathematics Equating Report. Table 7.3.1 shows the Rasch difficulty parameters and item fit statistics from WINSTEPS for the equating. Table 7.3.2 shows the fixed step parameters for the open-ended items. To create a Braille form a committee reviewed the 2003 Mathematics test items".
"No items were dropped from the 2003 NJ ASK Mathematics operational form to create the Braille form. A separate raw-to-scale score conversion table was not needed for the Mathematics Braille form in 2003. Part 8: Test Statistics. 8.1 Summary Statistics. Means and standard deviations of students’ raw scores on each content area are given in Table 8.1.1 for the May 2003 test. These data are based on the total Grade 4 student population described in Part 1. Table 8.1.1 shows that students’ mean raw scores were 23.1 of 43 points for Language Arts Literacy, and 25.8 of 42 points for Mathematics. The table also shows that the standard deviations of the raw scores ranged from 7.2 on Language Arts Literacy to 8.6 on Mathematics. Raw score to scale score conversion tables by content area are included in Appendix B. Also, frequency distributions of the scale scores by content area are shown in Appendix B” end quote".
