brain·wash [bráyn wòsh, bráyn wàwsh]
(past and past participle brain·washed, present participle brain·wash·ing, 3rd person present singular brain·wash·es)
transitive verb
1. impose beliefs on somebody: to impose a set of usually political or religious beliefs on somebody by the use of various coercive methods of indoctrination, including destruction of the victim's prior beliefs
Children in Primary do not have prior beliefs. Thus they cannot be brainwashed.
2. condition somebody to behave differently: to induce somebody to believe or do something, e.g. to buy a new product, especially by means of constant repetition or advertising

The key word is "differently", Tarski. Children in Primary are learning to behave/believe the first time. Thus they are not taught to behave "differently". They are not being taught to change.
And once a week does not come anywhere near "constant repetition".
