You need to understand why a PSA would rate you poorly.
* You may not be giving the right support needed, when it is needed.
* Your PSA may be looking for support that does not fit into SFI program.
* Your PSA may not be reading the available resources given and want to be you dependant.
When you are sure of the above, everything should flow well and with a personal relationship being developed, they should rate you five stars.
