Applying IRT requires statistical sophistication, which can be a barrier for "mom-and-pop" test developers such as classroom teachers who may not have the necessary training or resources to use this method effectively. While some teachers may have been trained in generalizability theory, this is not necessarily the most common or practical approach for classroom assessment. Additionally, IRT can be a useful tool for improving the quality and reliability of classroom tests, particularly for assessing student growth over time, but its advantages may not always be widely recognized or understood by educators.
