"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 these writing tasks, the rubrics used by the raters had score points that ranged from 0 to 5. If two raters assigned scores to a student’s writing task that were not exactly the same or adjacent, a third “expert” rater also read and assigned a score to the student’s response. Of more than 200,000
task responses in May 2003, 57.2% received exactly the same scores by the raters and 39.6% received scores that were adjacent. Thus, a total of 96.8% of the task responses required only two raters".
"The remaining 3.2% received scores on the Writing Tasks that differed by more open-ended items. For the reading open-ended items, the rubric used by the raters had score points that ranged from 0 to 4 or the three reading open-ended items, the resolution percent ranges from 2.9% to 4.3% with the five Mathematics clusters. These five mathematics items had percents at perfect agreement ranging from 75.8% to 88.0%. The percent requiring resolution ranged from 0.7% to 2.8%. One point and therefore required a third rater. The Reading cluster and the Mathematics content areas included. For the Mathematics items, the rubric ranged from 0 to 3 points. The percent at perfect agreement ranging from 55.4% to 58.3%. One open-ended item was presented for each of them. Part 9: Validity. Content and Curricular Validity".
"The New Jersey Department of Education is developing a comprehensive set of assessments that measure student achievement of the Core Curriculum Content Standards. The validity of the NJ ASK scores is based on the alignment of the NJ ASK assessments to the Core Curriculum Content Standards and the knowledge and skills expected of third- and fourth-grade students. The Standards for Educational and Psychological Testing (American Educational Research Association, American Psychological Association, & National Council on Measurement in Education, 1999, p. 11-12) notes the following possible sources of validity evidence. Evidence based on test content. Evidence based on internal structure of the test. Evidence based on relations to other variables. Evidence based on consequences of testing” end quote".
