"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 two designs have been called Backwards and Forward. The Backwards equating anchor items were operational items on the old form (e.g., 2002) and are in external sets on the new form (e.g., 2003). The Forward equating items were “pre-tested” as external sets on the old form (2002) and appear in the operational form on
the new form (2003). Performance on the Backward equating anchor items in 2003 indicate students in 2003 were slightly less able than in 2002, and the 2003 form was slightly more difficult than the 2002 form".
"After comparing the results of these two equating approaches, the recommended raw-score to scale-score conversion for the 2003 NJ ASK LAL test resulted from the Backwards approach. The recommended raw score cut points in 2003 for LAL were 18.0 and 35.0 for Proficient and Advanced Proficient categories, respectively. Details about the methods and results are described in the 2003 LAL Equating Report. Table 7.2.1 shows the Rasch difficulty parameters Measure, and item fit statistics from WINSTEPS for the Backwards equating solution. Table 7.2.2 shows the fixed step parameters for the open-ended anchor items. The raw-to-scale score conversion tables for Language Arts Literacy for 2003 may be found in Appendix B. To create a Braille form a committee reviewed the 2003 Language Arts Literacy test items. Items that could not be translated into Braille were dropped from the Braille version of the operational form".
"A separate raw-to-scale score conversion table was created for the Braille form. 7.3 Equating Mathematics. Scores on the 2003 NJ ASK grade 4 Mathematics form were equated back to scores on the 1999 Mathematics base form via 2001 and 2002 anchored Rasch difficulty parameters and using IRT true score equating procedures. The grade 4 base year Mathematics raw score scale ranged from 0-43.0. The base year raw cut score for Proficient was 23.0 (200) and the raw cut score for Advanced Proficient was 35.0 (250). These raw cut scores were derived from a standard-setting workshop in 1999. The data collection design for the NJ ASK Mathematics test is also Common-Item Non equivalent Groups design” end quote".
