Advantages of Artificial Intelligence (1) Zero human error Parallel forms reliability relates to a measure that is obtained by conducting assessment of the same phenomena with the participation of the same sample group via more than one assessment method.. Parallel-forms: Different people, same time, different test. This means that the scores could differ between the two tests simply because one half turns out to be more difficult than the other.
