Is it permissible to use older versions of standardized test instruments when revised editions have been published?
Consistent with regulatory requirements about the reliability and validity of test instruments and procedures, the most recent edition of a standardized test instrument should be used as soon as practicable (e.g., when the standardized instrument has become widely available, including the availability of training, if required by test developers) when conducting evaluations for the purpose of determining a child’s initial or ongoing eligibility for the EIP.
