Get the value of a field of the taxonomy term referenced with an Entity Reference field
The user is already associated with the boolean field via the taxonomy term.

For example, load your user's account:

global $user;
$account = user_load($user-&gt;uid);


Now load your taxonomy term:

$partner = taxonomy_term_load($account-&gt;taxonomy_field_name[LANGUAGE_NONE][0]['tid']);


And then get the boolean value of field_1:

$boolean_value = $partner-&gt;field_1[LANGUAGE_NONE][0]['value'];
