"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 “For items where the statistical test indicates significant differences (p < 0.05), the effect size is used to determine the direction and severity of the DIF. For the LAL OE items, the Mantel-Haenszel procedure was executed where item categories are treated as integer scores and a chi-square test was carried out with one degree of

freedom. The male and white groups are considered as reference groups and the female and other ethnic groups are categorized as focal groups".

"Based on these DIF statistics, items are classified into one of three categories and assigned values of A, B or C (see Table 6.4.1). Category A contains negligible DIF, Category B items exhibit slight or moderate DIF, and Category C items have moderate to large values of DIF. Negative values imply that conditional on the matching variable, the focal group has a lower mean item score than the reference group. In contrast a positive value implies that, conditional on the matching variable, the reference group has lower mean item score than the focal group. For constructed-response items the MH D-DIF is not calculated, but analogous flagging rules based on the chi-square statistic are applied, resulting in classification into A, B, or C DIF categories".

"Table 6.4.1. 2003 New Jersey Assessment of Skills and Knowledge (NJ ASK) DIF Categories. DIF Category. Definition A (negligible). MH D-DIF not significantly different from zero, or has an absolute value less than one. B (slight to moderate). MH D-DIF is significantly different from zero, and is either a) less than 1.5, or b) not significantly different from one. C (moderate to large). MH D-DIF is significantly different from one, and has an absolute value greater than 1.5. Operational items flagged for negative C (C-)DIF are reviewed by an expert DIF review panel consisting of NJDOE staff responsible for the NJ ASK, and external educators identified by NJDOE during the item review meetings, to ensure that the items are free from any bias before being used to produce final test scores” end quote".
