4 Expert rules let you evaluate the assessment data of an assessable course element and thus control the visibility and access to other course sections. To do this, use the expert rules **getScore, getPassed, getMark** or **getProgress**. These rules are also used to summarize and weight the assessment data in the Structure course element.

6 Another possibility is to transfer the assessment data to an Onyx test. For more information, see the section [[Variables>>doc:LMS.Benutzerhandbuch OPAL.Lehren.Kursbausteine.Test.KB Test Konfiguration.KB Test - Variablen.WebHome]] on the course element Test.

9 All of the following example rules can be created for both the **visibility **and **access** of a course element. To simplify matters, only one scenario is described in each of the following examples. To learn more about the difference between visibility and access, see the page [[Publishing within courses (visibility and access)>>doc:LMS.Benutzerhandbuch OPAL.Lehren.Kurs.Freigabe von Kursen und Kursinhalten.Freigabe innerhalb von Kursen Sichtbarkeit und Zugang.WebHome||shape="rect"]].

21 In all of the following examples, specific course elements are used. Before using these rules, note down the relevant course element IDs for your scenario and adjust them accordingly in the expert rules.

74 Create additional rules by using expert syntax. A tabular overview is provided on the page [[Expert syntax>>doc:LMS.Benutzerhandbuch OPAL.Lehren.Kurs.Freigabe von Kursen und Kursinhalten.Expertenmodus zur Freigabe innerhalb von Kursen.Expertensyntax.WebHome]].
