Unless you add name attribute to form level field, that will not get included in form object when you specified in the name attribute on form, currentlyh it is name="studentForm". Do add name="firstName" to your input field

<input type="text" class="form-control" 
  name="firstName" ng-model="formsToBeValidated.firstName" required/>

More convenient way to solve this issue would be using ng-messages instead of using ng-show/ng-hide, for that you have to include ng-messages module with its ng-messages dependency.
