I first gave an adaptive computerized reading inventory to all 106 of the 6th graders at my school on October 1; I gave the second one on Feb 25. Unfortunately, the results of these inventories seem highly anomalous. Forty-six kids actually posted negative growth; some posted negative growth of over 350 lexile points. Since it is highly unlikely that these kids regressed in their ability to read, I can only question the validity of the reading inventories. Anecdotal evidence I have made reference to earlier in this blog, suggests that some students may not have done their best on the second assessment in fear that they would have to read harder books as a result.
Overall, average growth for all sixth graders was 23 lexile points.

Hi Matt,
In my experience it is not uncommon to see negative growth on the reading inventory. You are right, sometimes the test just gets too long, and they get bored with it. Or, if they have figured out that the better they do, the harder books they'll have to read, they may do poorly on purpose.
I'll send you my sixth grade data from last year, just as a comparison.

Thanks for the data. I noticed that in the latest version of SRI the program does not show negative scores. I've read that some people like Renaissance's STAR reading inventory more than SRI because it doesn't take as long to complete: six minutes on average compared to over 20 minutes for the Scholastic product.
