California's school accountability system was originally based solely on scores from the CAT/6. Through the Academic Performance Index (API), the scores drove the allocation of millions of dollars in intervention and award programs, depending on the health of the state’s budget. (The state has not funded award or intervention programs based ...
The Northwest Evaluation Association (NWEA) [1] [2] is a division of Houghton Mifflin Harcourt (acquired by HMH in 2023) that creates academic assessments for students pre-K-12. NWEA assessments are used by over 50,000 schools and districts in 149 countries. [3] There are over 16.2 million students using NWEA. [4]
With a norm-referenced test, grade level was traditionally set at the level set by the middle 50 percent of scores. [10] By contrast, the National Children's Reading Foundation believes that it is essential to assure that virtually all children read at or above grade level by third grade, a goal which cannot be achieved with a norm-referenced ...
The reason for the choice of the number 21.06 is to bring about the following result: If the scores are normally distributed (i.e. they follow the "bell-shaped curve") then the normal equivalent score is 99 if the percentile rank of the raw score is 99; the normal equivalent score is 50 if the percentile rank of the raw score is 50;
The figure illustrates the percentile rank computation and shows how the 0.5 × F term in the formula ensures that the percentile rank reflects a percentage of scores less than the specified score. For example, for the 10 scores shown in the figure, 60% of them are below a score of 4 (five less than 4 and half of the two equal to 4) and 95% are ...
MAP-A - There is also the MAP-Alternate (MAP-A) designed for students with severe cognitive disabilities who meet grade level and eligibility criteria. [1] Communication arts is assessed at grades 3-8 and 11, math is assessed at grades 3-8 and 10 and science is assessed at grades 5, 8 and 11. Missouri does not have a 2% modified assessment.
Citing a disproportionate number of students scoring in the 99th percentile — the far right tail of the distribution curve — the NYC DOE replaced the Bracken (BSRA) with the Naglieri Nonverbal Ability Test (NNAT), and changed the weighting, lowering the OLSAT from two-thirds to one-third and giving the NNAT two-thirds.
Norms provided for the 1978 edition include standard scores with a mean of 100 and a standard deviation of 15, percentile scores, and grade levels. The standard scores are scaled based on the norm group; the grade levels are arbitrarily assigned and can be interpreted only as rough references to achievement level. Only standard scores should be ...
