Restrict a menu item only for a particular accessible after loggin and optionally for a role
If you actually just want to check if the user is logged in and don't want to set up permissions, you can set the access callback to 'user_is_logged_in':

$items['start'] = array(
  'title' =&gt; 'Take A Test',
  'page callback' =&gt; 'qe_start',
  'access callback' =&gt; 'user_is_logged_in',
  'expanded' =&gt; TRUE,
);
