OneRoster is a standard from 1EdTech that allows for the secure exchange of enrollment data between 2 platforms. Many SISs allow enrollments to be exported via the OneRoster format. This OneRoster file can then be uploaded into a OneRoster-compliant platform or application. OneRoster contains data such as names, email identifiers, course listings, and roles of users.


Clever is a popular platform to obtain roster data. Clever helps school administrators to connect SISs to Clever. The students and teachers from a school can then log into Clever-connected apps with a single set of credentials. This entire process is free for schools. However, companies who want to be able to retrieve rostering data from Clever must pay for Clever's Secure Sync program.

ClassLink provides SSO and rostering solutions for educational applications. ClassLink's services (which include Launchpad, OneSync, and Roster Server) are built on the OneRoster standard.

Roster Server is ClassLink's implementation of a OneRoster server. Schools that work with ClassLink will install Roster Server as a virtual server on the school’s network or in the cloud. School administrators then either directly connect an SIS to Roster Server through the OneRoster API or upload CSV templates into Roster Server that are formatted in the OneRoster specification.

When school administrators connect to a learning application on ClassLink, the school's Roster Server will export the school’s enrollments to the application through the OneRoster standard. Though it's not required, many edtech apps will use this data through ClassLink Launchpad in order to provision accounts for users and enable SSO.


GG4L offers rostering through its GG4L Connect solution. GG4L creates universal identifiers for school users through SIS, LMS, and LDAP integrations. GG4L exposes its roster data through the OneRoster API standard.


Ed-Fi is a non-profit organization that promotes the use of its Ed-Fi data standard and the Ed-Fi API. Edtech vendors that work with districts that have adopted the Ed-Fi technology suite can use the Ed-Fi API to roster data into their applications.

It is important to note that Ed-Fi itself is not a product or rostering tool. It is a standard that other products can adhere to. There are a number of products on the market that implement the Ed-Fi specification, including Powerschool and Certica.


A4L is another non-profit that encourages the use and development of data standards for education, such as the SIF specification. A4L offers the xPress Roster API as a method to retrieve rostering data from schools that support SIF 3 data models.

LMS Integration

Many LMSs allow for the retrieval of enrollments and other related data via their API. This method may require an administrator or teacher to connect the school’s account to the application. At this point, the app may retrieve a list of enrollments from the user's courses in the LMS. It should be noted that the LTI Advantage standard can also gather enrollment data for a particular course, but not for an entire school.

Manual or CSV-based Rostering

Many applications allow users to upload roster information manually. This is certainly the most error-prone and time-consuming method to perform rostering. But it may be necessary that a school or app does not support any of the previously mentioned methods for rostering. This process can either be performed by allowing admins to create accounts for other users through an interface in the application. Or allow the user to upload rosters through a specified CSV format.
