Introduction

Talview’s proctoring solutions for Moodle LMS include two essential plugins: the Quiz Access Proctor plugin and the Local Proview plugin. These plugins work together to enhance the security and integrity of online quizzes by integrating advanced proctoring features directly into Moodle’s quiz module. The Quiz Access Proctor plugin allows educators to apply specific proctoring settings to their quizzes, ensuring a controlled testing environment. With this plugin, different types of proctoring can be configured, and Talview’s Secure Browser can be utilized to prevent unauthorized access and maintain exam integrity. Install the “quiz access proctor” plugin first Complementing this, the Local Proview plugin injects the necessary Proview JavaScript into Moodle quizzes. It ensures that the proctoring session is initiated correctly when a quiz starts and manages integration aspects such as fetching session playback URLs for post-exam review. This comprehensive approach allows for seamless monitoring and reviewing of proctored sessions, enhancing the overall assessment process. Install the “local proview” plugin second

Process to Insert Missing Quiz Records into mdl_quizaccess_proctor

​
1. SQL to Identify Missing Records

This query identifies quizzes in mdl_quiz that do not have a corresponding entry in mdl_quizaccess_proctor. 
SELECT q.id AS quizid, q.course AS courseid, cm.id AS cmid
FROM mdl_quiz q
LEFT JOIN mdl_course_modules cm ON cm.instance = q.id AND cm.module = (
    SELECT id FROM mdl_modules WHERE name = 'quiz'
)
LEFT JOIN mdl_quizaccess_proctor p ON q.id = p.quizid
WHERE p.quizid IS NULL;

​
2. SQL to Insert Missing Records

To insert missing records with default values, use the following query. 
INSERT INTO mdl_quizaccess_proctor (
    quizid, cmid, proctortype, tsbenabled, usermodified, timecreated, timemodified,
    reference_link, instructions, blacklisted_softwares_win, blacklisted_softwares_mac,
    sb_kiosk_mode, sb_content_protection
)
SELECT
    q.id AS quizid,
    cm.id AS cmid,
    'noproctor' AS proctortype,
    0 AS tsbenabled,
    2 AS usermodified,
    UNIX_TIMESTAMP() AS timecreated,
    0 AS timemodified,
    '' AS reference_link,
    '' AS instructions,
    '' AS blacklisted_softwares_win,
    '' AS blacklisted_softwares_mac,
    0 AS sb_kiosk_mode,
    0 AS sb_content_protection
FROM
    mdl_quiz q
LEFT JOIN
    mdl_course_modules cm ON cm.instance = q.id AND cm.module = (
        SELECT id FROM mdl_modules WHERE name = 'quiz'
    )
LEFT JOIN
    mdl_quizaccess_proctor p ON q.id = p.quizid
WHERE
    p.quizid IS NULL;

​
3. Verification

After running the query, verify no quizzes are missing 
SELECT q.id AS missing_quizid
FROM mdl_quiz q
LEFT JOIN mdl_quizaccess_proctor p ON q.id = p.quizid
WHERE p.quizid IS NULL;
