Q&A – Rate of improvement for EasyCBM

ROI6

Great question from Leasha:

Please help! Our new state policy manual has listed your website as the place to go for calculating our rate of learning for the upcoming school year. Pretty much every county in the state uses Dibels so it is set up and ready to go for them. However, my county uses EasyCBM for reading. Is it possible for me to just edit the benchmark goals, and then the Excel would calculate it properly for students entered, or would I need to do some special tweaking?

My Response:

Absolutely! You can adjusts the benchmarks to whatever you need them to be and the Excel sheet should automatically adjust the calculations for ROI.  Good luck!

Q&A – Slope for standard scores

ROI6

Great question from Lavonne:

My question is similar to that of Jen on July 18, 2011. I am wondering if Rate of Improvement can be graphed and slope comparisons used with standard scores such as those generated by STAR Reading. We also have standard scores on our statewide assessments and could easily generate Excel graphs to show the difference between our student’s performance and that reuqired to pass. We can easily generate our own Excel graphs, we just want to make sure the data is valid.Thank you.

P.S. Thanks so much for this site!

My response:

You can calculate slope for scores that have an equal interval between data points.  STAR Reading, STAR Math, and STAR Early Literacy is a good example of non-CBM data and has been validated as a data set for which you can calculate slope.  Joe Kovaleski and colleagues (2013) just published a book that describes using rate of improvement with computer adaptive tests (CATs), specifically with STAR assessments. I highly recommend getting a copy!

PA RtI Implementer’s Forum

Gearing up to present with Andy McCrea tomorrow as part of PaTTAN’s RtI Implementer’s Forum tomorrow. As Andy and I were updating the PowerPoint this past week, we realized we’ve been speaking on this topic for 5 years now! It’s been interesting to see the evolution of awareness in our participants over time. Many more participants have access to curriculum-based measurement (CBM) data than when we first started. Even more have figured out how to graph data and generate trend lines in Microsoft Excel, some without realizing they are essentially computing linear regression statistics! We’ve presented for a range of audiences that started out as mainly school psychologists but has expanded to teams who are implementing components of RtI in their schools. Tomorrow’s workshop is formatted for just that – teams! Should be another great interactive workshop!
