The nature of job or duties to be performed by the teacher will also have to be kept in mind. It will also have to be kept in mind whether the teacher will be overage for similar employment if he/she is not confirmed. Keeping in mind all the relevant facts, probation period, except in exceptional cases, so far as a teacher is concerned, should not continue beyond a period of 5 years from the first date of appointment. Even a period of 4/5 years has to be really in a very grave and exceptional case depending on the facts of that case. However, I do not express myself finally with respect to what should be a reasonable period between 3 to 5 years because Courts will necessarily examine that aspect in the facts and circumstances of each individual case. I am making these specific observations with respect to the maximum period of probation being ordinarily only of 5 years because in the absence of fixing an outer limit by the statute viz Rule 105, the entire purpose of a probation period and a probationary teacher being confirmed would be defeated by the machinations of the management of the schools in certain cases thus affecting education and bringing in of Article 21A in the Constitution. Therefore, I hold that the Rule 105 must be so interpreted that the reasonable period therein should ordinarily be around three years, should not extend beyond five years in most of the cases, and, in the rarest or rare cases, one more year upto 6 years may be considered. However again at the cost of repetition it is stated that six years period is being observed only as a most grave and rarest of rare circumstance in a case, and ordinarily, a probation period qua a teacher should not extend beyond/around three years which is a reasonable period, and as per the facts and circumstances of certain case,
