Abstract :Automated Test Assembly (ATA) plays important role in test development, especially in large scale test administrations. However, there is a lack of tutorials showing how to solve ATA problems. This tutorial aims to show to how build on-demand test forms easily for researchers and practitioners, and share the R codes for their use. The study presents the annotated R codes for thirty-nine unique examples. The examples include building one form, multiple forms and more complex ones under different constraint conditions across equal or different form lengths. All examples were solved by using “xxIRT” R package. The graphical depictions of the form-level information functions for all examples were also provided. Some important notes about the codes were also provided at the end of the paper in case one did not find a solution. The thirty-six examples were provided in the main body of the paper, the other three complex examples were given in the Supplementary material.
