Multiple table inheritance in Laravel 5.1

I've read some comments about how to implement multiple table inheritance in Laravel, but I'm confusing.

In this thread (Table inheritance in Laravel), I noted that a table inheritance was implemented. However, Laravel 5.1 documentation explains about "Polymorphic Relations" (http://ift.tt/1RvSF2y).

This is my scenario: A "Person" can be a "Student", "Teacher" and/or "Candidate". The same person can be Student and Teacher at the same time, for example. This is a way to implement the models I think (I do not know if it is correct):

class Person extends Model {
    public function teacher(){
        return $this->hasOne(Teacher::class);
    }
    public function student(){
        return $this->hasOne(Student::class);
    }
    public function candidate(){
        return $this->hasOne(Candidate::class);
    } 
}

class Student extends Person {
    public function person(){
        return $this->belongsTo(Person::class);
    }
}

class Teacher extends Person {
    public function person(){
        return $this->belongsTo(Person::class);
    }
}

class Candidate extends Person {
    public function person(){
        return $this->belongsTo(Person::class);
    }
}

In the database, I would create the tables:

• Person (id, name, phone)
• Student (person_id, etc)
• Teacher (person_id, etc)
• Candidate (person_id, etc)

This way, I do not use Polymorphic Relations as Laravel 5.1 explains. Any suggestions about the best way to accomplish this?

Thank you very much.
