Please use the following link to run the PIRLS System Check:
A green background and checkmark indicate compatibility, whereas a red background and “X” indicate incompatibility with the required configuration. If any device configuration receives a red background and “X,” the device cannot be used for PIRLS administration unless reconfigured. If the school contact or IT specialist determines the incompatibility can be readily reconfigured, please resolve the issue and run the PIRLS System Check program again. If the incompatibility remains, the device cannot be used for PIRLS.
If all requirements are cleared by a green background and checkmark, the verification was successful. For best results, run the PIRLS System Check on a minimum of three devices intended for administration.
