Requirement for HAAD EXAM

Hi, good day everyone.
I would like to confirm if the 2 years experience required to take the HAAD must compose of 1 year from Med-Surg ward and 1 year area of specialty.
In my case, the 2 years experience that i had as a staff nurse is a 1 month rotation in all areas of the hospital like med-surg ward, pedia ward, Emergency room. Is this acceptable? anyway it is still counted as 2 years experience in the hospital.
Please help.
Thank You.
