Hi dear. I am sorry to know the problem regarding transfer of your wife.
I think the Words “same category” under para “d” of Rule “3” of the said G.O. restricts her to get transfer to a Higher Secondary school.
d) the Incumbents concerned opting for mutual transfer shall be from the same category of schools, having same medium of instruction i.e. Bengali or English or Hindi or Nepali or Oriya or Santhali or Telegu or Urdu or Bengali-Urdu;
