"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 “When the decisions were collapsed to below proficient versus proficient and above, the estimated proportion correctly classified was 0.92. Estimated Proportion Correctly Classified: Total = 0.83, Proficient and Above = 0.92. 8.4 Conditional Estimate of Error at Each Cut-Score. When reviewing a cut score, it is important to keep in mind that there is measurement

error surrounding that cut score. Measurement error occurs because no instrument measures a student’s level of knowledge and skills precisely. Think of the student who knows the correct answer to an item, but makes a careless arithmetic error or accidentally marks the wrong response".

"Think of a student who really does not know the correct answer but who fills in the correct answer purely by chance. These situations require us to calculate a standard error of measurement for each score. For example, let’s say a student scores a 28 (out of 43) and the standard error of measurement for the score is about 2.0 raw score points. We can be 95% confident that the student’s ability put him in the range of scoring a 28 plus or minus two standard errors of measurement: that is between 24–32. The WINSTEPS program calculates the standard error of the measure (SEM) at each score point. Unlike the classical standard error of measurement, the value of the SEM using Item Response Theory varies with ability level".

"The equation for standard error of estimation is given by ()1 ˆ SE ? ()I? = 8.4.1] [ where ()I? is the information function for a test at ?. For the Rasch model using unweighted raw scores, the information provided by a test at ? is the sum of the item information functions at ? (Hambleton, Swaminathan, and Rogers, 1991). Table 8.4.1 shows conditional estimates of error at each cut score for each subject. 8.5 Rater Reliability Table 8.5.1 shows the percentages of writing tasks a T and open-ended items scored with exact agreement, adjacent agreement, and resolution needed. The Writing cluster within Language Arts Literacy consists of two writing activities: a writing/speculate task in response to a picture and a writing/analyze task related to a poem” end quote".
