Since these are standardized tests, that means that the range of scores within a given level is determined by the mean for that year and the standard deviations around the mean. Last year's "4" could be this year's "3" is the mean shifted upwards, which is why standardized tests actually tell us very little about individual progress. You can't "pass" a standardized test - the entire notion that you can is a fallacy and this fallacy being preached as gospel is ruining the educations of students and the careers of educators.<br /><br />On another note, if a student takes the grade 3 test and scores a scale score of, say, 650, Level 2 and the following year takes the 4th grade test, scoring another 650, level 2, has he made a year of progress? Think carefully.<br /><br />YES HE HAS. Because the student is taking the FOURTH grade test and has HELD HIS POSITION on the curve, he HAS indeed made one year of progress, even with the scores the same. Why? Because the 4th grade test is ONE YEAR MORE difficult than the 3rd grade test, so to hold position on the curve, one year of progress is required. The only time you can expect scores to go up in relation to progress would be if he took the 3rd grade test in 3rd grade, and in 4th grade took the 3rd grade test AGAIN.<br /><br />I could go on but all this statistics talk has probably put most readers to sleep already. I'll save standard errors of the mean and standard deviations for another day.bookwormnoreply@blogger.comtag:blogger.com,1999:blog-33431390.post-45251808052776501142011-09-29T13:05:02.265-04:002011-09-29T13:05:02.265-04:00what a total crock of shitwhat a total crock of shitAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-33431390.post-70797055756162154182011-09-28T12:45:18.664-04:002011-09-28T12:45:18.664-04:00You do know that the "levels"change from...You do know that the "levels"change from grade to grade, don't you?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-33431390.post-56446232850020823452011-09-27T19:53:45.691-04:002011-09-27T19:53:45.691-04:00My son has an IEP so I have heard of the challeng...My son has an IEP so I have heard of the challenges all educators face with ARIS. My son is in 8:1 and at level 2-he has been through 3 years. <br />I don't expect a years growth every year for a child with profound challenges, but over 3 years I expect level 2 to become level 3.<br /><br />You know what I find profoundly disturbing, that you know a child comes to you at level 2 and you let him leave the same way.Anonymousnoreply@blogger.com
