At her jury trial in Auckland this month the Crown said: "She never, ever passed that diploma and we know that she never received that final qualification. But she seemed to forget that."
Court documents state Hibberd, 33, failed one of her final papers for the second time in April 2010 at NZ Tertiary College. The college agreed to let her sit for a third time, but she instead gave Clevedon Kidz a letter and academic record showing she had completed a Diploma of Early Childhood Education.
She later provided more forged documents but later said in her defence a Clevedon Kidz manager had forged the documents.
She is due to be sentenced on April 24.
