Pyslet: Python package for Standards in Learning, Education and Training

Project description

Build Status

Pyslet is a Python package for Standards in Learning Education and Training (LET). It implements a number of LET-specific standards, including IMS QTI, Content Packaging and Basic LTI. It also includes support for some general standards, including the data access standard OData (see

Pyslet was originally written to be the engine behind the QTI migration tool but it can be used independently as a support module for your own Python applications.

Current Status & Road Map

Pyslet is going through a transition process at the moment as the QTI migration tool that drives its development is gradually moving towards being distributed as an LTI tool rather than a desktop application.

The OData support is fairly robust, it is used to run the Cambridge Weather OData service which can be found at

What’s next?

  • Proper Media stream support in the OData SQL storage model
  • MySQL shim for the OData SQL storage model
  • Improved support for LTI to take it beyond ‘basic’

I’m also slowly transforming the code for better PEP-8 compliance as reported by the fantastic flake8.

I write about Pyslet on my blog, which is a good place to find out what’s new:


The code is now maintained on Github (version 0.5 and later): - the best way to get something changed is to create an issue there.

Some historical information is available on QTI Migration tool’s Google Code project:

You can find out more about me and contact me directly through my Google profile page linked from my blog page.

Pyslet is written and maintained by the main author on a spare time basis and is not connected to my current employer.

As I don’t have much spare time, the code tends to be fairly stable. Some of the code was written almost 20 years ago and it owes a lot to the University of Cambridge that employed me for many years in a variety of different roles.


Pyslet is distributed under the ‘New’ BSD license:, this decision was inherited from the early days of the code. Although Copyright to much of the source is owned by the author personally earlier parts are owned by the University of Cambridge and are marked as such.
