WHEN Cynthia Stevenson, the superintendent of Jefferson County, Colo., public schools, heard about a data repository called inBloom, she thought it sounded like a technological fix for one of her bigger headaches. Over the years, the Jeffco school system, as it is known, which lies west of Denver, had invested in a couple of dozen student data systems, many of which were incompatible.

In fact, there were so many information systems — for things like contact information, grades and disciplinary data, test scores and curriculum planning for the district’s 86,000 students — that teachers had taken to scribbling the various passwords on sticky notes and posting them, insecurely, around classrooms and teachers’ rooms.

There must be a more effective way, Dr. Stevenson felt.

InBloom, a nonprofit corporation based in Atlanta, seemed to offer a solution: it could collect information from the district’s many databases and store it in the cloud, making access easier, and protect it with high-level encryption.

The company has name-brand backing: $100 million in seed money from the Bill and Melinda Gates Foundation along with the Carnegie Corporation of New York. Beyond storing data, it promised to help personalize learning — by funneling student data to software dashboards where teachers could track individual students and, with the right software, customize lessons in real time. Also, districts could effortlessly share student records with developers seeking to create educational tools for schools. In other words, for Dr. Stevenson, it represented not just a fix to a narrow technical problem, but also a potentially revolutionary way to help educate students.
