You can use the workscout_reviews_criteria filter to modify the criteria by adding code to your theme’s functions.php file (preferably  or in a plugin. Here are several examples:

Adding New Criteria

function modify_workscout_reviews_criteria($criteria) {
    // Add new criteria
    $criteria['timeliness'] = array(
        'label' => esc_html__('Timeliness', 'workscout-freelancer'),
        'tooltip' => esc_html__('Ability to meet deadlines and deliver work on time', 'workscout-freelancer')
    );
    
    $criteria['creativity'] = array(
        'label' => esc_html__('Creativity', 'workscout-freelancer'),
        'tooltip' => esc_html__('Creative problem-solving and innovative approach to work', 'workscout-freelancer')
    );
    
    return $criteria;
}
add_filter('workscout_reviews_criteria', 'modify_workscout_reviews_criteria');

Removing Existing Criteria

function remove_workscout_criteria($criteria) {
    // Remove specific criteria
    unset($criteria['communication-skills']);
    
    return $criteria;
}
add_filter('workscout_reviews_criteria', 'remove_workscout_criteria');

Modifying Existing Criteria

function update_workscout_criteria($criteria) {
    // Modify existing criteria labels or tooltips
    if (isset($criteria['quality'])) {
        $criteria['quality']['label'] = esc_html__('Work Quality', 'workscout-freelancer');
        $criteria['quality']['tooltip'] = esc_html__('Overall quality and accuracy of delivered work', 'workscout-freelancer');
    }
    
    return $criteria;
}
add_filter('workscout_reviews_criteria', 'update_workscout_criteria');

Completely Replace Criteria

function replace_workscout_criteria($criteria) {
    // Replace with entirely new criteria
    return array(
        'expertise' => array(
            'label' => esc_html__('Technical Expertise', 'workscout-freelancer'),
            'tooltip' => esc_html__('Level of technical skill and knowledge demonstrated', 'workscout-freelancer')
        ),
        'reliability' => array(
            'label' => esc_html__('Reliability', 'workscout-freelancer'),
            'tooltip' => esc_html__('Consistency in delivering promised results', 'workscout-freelancer')
        ),
        'value' => array(
            'label' => esc_html__('Value for Money', 'workscout-freelancer'),
            'tooltip' => esc_html__('Quality of work relative to cost', 'workscout-freelancer')
        )
    );
}
add_filter('workscout_reviews_criteria', 'replace_workscout_criteria');
