Controller .... 

    function getCompetencias(){
        $query['competencia'] = $this->studentCompetencias_model->getCompetencias();
        $encon = json_encode($query);

        $student = $_POST['alumno'];
        $teacher = $_POST['clase'];
        $queryA['atributo'] = $this->studentCompetencias_model->getAtributos($student,$teacher);
        $enconA = json_encode($queryA);

        echo $encon,$enconA;
}

JQuery (AJAX) 

$.ajax
          ({
            type: 'POST',
            data: {alumno: id, clase: idAsgin},
            url: '<?= base_url()?>EvaluarCompetencias/getCompetencias',
            success: function(data){
              var obj = JSON.parse(data);
              alert(obj);
            },error: function(){
              alert("algo salio mal");
            }
          });

With an associative array 

echo json_encode( array( 'vocales'=> ['a','e','i'], 'numeros'=>[1,2,3]) );

And in your success function you will have this structure that you can work easily 

{"vocales":["a","e","i"],"numeros":[1,2,3]}

When using associative array, and to be able to extract the data, the positions of the array must be added first, then the name of the array after the position of the data and at the end the data.

obj [0] ['competition'] [i]. final data;
