If your ASLPI result is lower than what you expected and/or it does not meet a needed requirement, it will not benefit you to schedule another ASLPI immediately. If your language skills have not improved, a higher proficiency level will not be awarded. Consider seeking out both formal instruction and interactive opportunities. Both are typically needed to improve language skills.
Please check out the ASL Class information.
If you decide to schedule again, each evaluation costs the same. There are no reduced rates.
