adaptivetesting 1.0.1

adaptivetesting is a Python package that can be used to simulate and evaluate custom CAT scenarios as well as implement them in real-world testing scenarios from a single codebase

adaptivetesting

adaptivetesting is a Python package for computerized adaptive testing that can be used to simulate and implement custom adaptive tests in real-world testing scenarios.

Getting Started

Required Python version: >= 3.11 (other versions may work, but they are not officially supported)

pip install adaptivetesting

If you want to install the current development version, you can do so by running the following command:

pip install git+https://github.com/condecon/adaptivetesting

Features

• IRT-Models:
  • 4PL
  • simplified derivates (e.g., 3PL, Rasch model)
• Ability estimators:
  • Maximum Likelihood Estimation
  • Bayes Modal
• Item selection algorithm:
  • Urry’s rule
• Stopping criteria:
  • test length
  • ability estimation standard error
• Test results output formats
  • SQLITE
  • Pickle
• Functions and wrappers for CAT simulations and application implementations

Any functionality can be modified and extended.

Implementations

The package comes with two CAT implementations that are ready to use.

Default implementation

Semi-Adaptive implementation

Custom testing procedures

Custom testing procedures can be implemented by implementing the abstract class AdaptiveTest. Any existing functionality can be overridden while still retaining full compatibility with the packages' functionality. For more information, please consult the documentation for the AdaptiveTest class.

Package structure

submodule	description

services	interfaces that concrete implementations inherit from
simulations	functions and classes used in CAT simulation
tests	Unit test for the entire package
