An algorithm designed to spot struggling students and offer guidance and assistance even in the first couple weeks of their college career proved highly effective at Purdue University over the past six years.


Signals was first used at Purdue University in 2007.

The program, known as Signals, is one of the first advanced analytics programs to identify at-risk students by delving into reams of data that offer a clear picture into how a student in adjusting to her college education.

Signals examines numbers gathered from more than 20 data points stemming from learning management systems used at Purdue.

Purdue students enrolled in at least two courses that used the Signals program graduated within six years at a 21.5 percent rate higher than students who didn’t take classes that used Signals, according to statistics released by the university.

Campus technologists have long pushed for widespread adoption of analytics that could improve retention rates, emphasizing that technology could serve as a central piece of a larger effort to keep students in school, on a path toward graduation.

“Academic analytics can help shape the future of higher education, just as evolving technology will enable new approaches to teaching and learning,” Kimberly Arnold, educational assessment specialist for Purdue’s Teaching and Learning Technologies group, wrote.

Arnold added that beyond applying analytics programs like Signals, “effective teachers will continue to interact with their students; students will continue to work cooperatively and be accountable for their own education; feedback will continue to be important.”
