Hannah is creating two versions of the test (parallel forms) and assessing the consistency of the scores obtained by individual observers using the two different versions. This is an example of parallel-forms reliability. Inter-rater reliability would involve having different observers score the same children using the same version of the test, test-retest reliability would involve administering the same test to the same children on two different occasions, and internal consistency reliability would involve assessing the consistency of responses within the same test (e.g., do items within the test consistently measure the same construct?).
