Answer 1

You don't need ng-value . Use only ng-model and set the $scope.aprv value to true or false .

<input type="checkbox" ng-model="aprv" name="attestorFlag" id="attestorFlag">

Controller:

if ($scope.attestorObj.attestationStatus === 'approved') {
    $scope.aprv = true;
}

you could add the condition to your checkbox itself by adding the ng-checked. think this should work for you, hope this helps or gets you in the right direction

        <div class="col-md-3">
            <label class="radio-inline">
                <input type="checkbox" 
                    ng-checked="$scope.attestorObj.attestationStatus == 'approved'"
                    ng-model="aprv"
                    name="attestorFlag" id="attestorFlag"> I attest </label>
        </div>
