Issues Fraud Triangle Threats • Rationalization • Opportunity • Motivation • Impersonation • Content Theft • Cheating
Low/High to High/High Stakes Tests What’s at Stake? Higher Stakes Life and Limb Promotion & Jobs & Legal Concern Educational Exams Tests Elearning & Surveys

Authoring: Item Banking and Security • Security impacts • Validity of assessment results • Fairness to participants • One approach: security rights that are role-based • Set access permissions by role or profile • Limit an author’s or reviewer’s access to the various functions • Limit access to topic (item) folders • Limit what the author may do in those folders
Scheduling • Create participants and schedule assessment delivery • Manage participants individually or in hierarchical groups • Schedule access to assessments: • Limit dates • Limit attempts • Require proctor/invigilator • Deliver to certified test center • Online or offline delivery • Email Broadcast:Notifications to Participants
Blended Delivery Levels of Monitoring Stakes of Assessment
Secure Browser Regular Browser Questionmark Secure • Stops people from printing questions • Stops people from typing in their own URL • Always display in full screen and it’s not possible to maximize or minimize • Stops people starting a new task • Does not provide menu options or icons • Disables control keys and task switching • Disables right-click menu options • Disables the ability to start new applications • Prevents going backwards to a previous page • Stops people exiting in a high stakes, proctored, environment • Hides the HTML source • Provides an API to control certain functions of a browser from the server • Server can command Questionmark Secure to display a toolbar
Browser Check Ensures Test Takersuse a compatible browser
Delivery Security • Perception can be configured to use SSL to ensure communication between participants and the server are secure • Data in item repositories are encrypted (QML is encrypted) providing added item bank security • All participant scoring is conducted on the Perception server (rather than on client/participant PCs) • Scoring algorithms are not sent in any way to participant PCs
Limiting Item Exposure • Question by Question (QxQ) delivery options limit the amount of content shown at one time • Randomization of questions and choices to prevent cheating
Reporting • Score List Report • IP addresses (as expected?) • Time taken (too quick, too long?) • Easy flagging of participants who get perfect scores for further investigation • Coaching Report • Drill down on an individual participant, comparison to benchmark, use in appeal process • Item Analysis Report • Determine psychometric performance and examine item difficulty drift over time • Test Analysis Report • Assessment defensibility review and test difficulty drift
Case studies Case studies from Creighton University • What their test security needs were • How our software addressed those needs • Demo of solutions
Creighton University School of Pharmacy & Health Professions • Private Jesuit University located in Omaha, NE • 2001 started the first and only accredited truly distance based full time Doctor of Pharmacy program • Issues to resolve and security requirements • How to securely deliver and administer exams to students located throughout the country • Paper and pencil were too expensive and it’s difficult to distribute and collect approximately 5600 exams per semester • Control who sees what test and when • Lock down the computer to eliminate printing, instant messaging, browsing the internet during the tests • Ability for students to “mark” an identified area of a graphic
Creighton University School of Pharmacy & Health Professions Solutions offered to meet requirements: • Provided online testing solution and eliminated almost all paper and pencil tests to reduce costs • 22 Question types including Hotspot allowing online exams to replicate past paper exam formats with the additional ability to provide instant feedback. • Ability to randomly deliver different variations of an exam • Manage large item banks of questions including security for collaborative authoring among faculty • Lock down browser • Scheduling (right test to right student) Demos • Hotspot question type & feedback text/images • Password system & variations of an exam • Item Banking and security for collaborative authoring • Questionmark Secure • Scheduling

Remote Video Monitoring Custom Hardware Laptops and PCs
Candidate (Participant) Logs in As Software Secure and Questionmark integration is for higher stakes exams a Participant will be referred to as a Candidate
Schedule Appointment Exam Candidate selects exam and “Schedules Appointment” Exams (4) Surveys (1)
Review Schedule If the exam is to be schedule in the next 3 days or if the participant might be expected to pay some of the cost of the exam then there are more steps
Selects Exam to Take Exams (4) Surveys (1)
ProctorU / Software Secure • Camera and Microphone Access • Identity Checks • Captures Photo, Proctor Checks against files • Proctor checks has Participant scan the room
Security Checks Complete Candidate Takes Exam • After Authentication Candidate takes Exam • Video and screens are monitored during exam
Mobile Test Centers • Use notebooks/3G laptops/iPads to create mobile test centers • Enables greater flexibility in where you deliver assessments • Assessments can be conducted in ‘on location’ environments Slide 10
“Securing” an iPad… • An app should prevent candidates from easily getting to other URLs • But – access to “home button” allows task-switching • Hardware solutions are available to enable use of iPad in a “kiosk” mode Slide 11
Considerations: • The higher the stakes, the higher the propensity to cheat –still require human monitoring! • Bandwidth – Be sure to test the wifi and/or 3G signal strength prior to event Slide 12
Considerations for cheat-resistant questions and assessments Randomization Refresh items regularly Build large item banks Track item parameters Tests that are unique for each test taker make it hard to share answers Adaptive tests provide different questions based on responses to previous questions
Improve Your Multiple Choice Questions Answer choices should be roughly the same length and kept as short as possible. Provide a minimum of three answer choices and a maximum of five. Four is considered optimal. Keep your writing clear and concise – you’re testing knowledge, not reading comprehension. Make sure that you’re putting the correct answer in the first two positions as often as the last two positions.
Extended Matching Question Type • The number of answer options depends on the logical number of realistic options for the test taker.) • The same answer choice could be correct for more than one question in the set • Some answer choices may not be the correct answer for any of the questions • So it is difficult the answer this type of question correctly by chance. • A well-written lead-in question is so specific that students understand what kind of response is expected, without needing to look at the answer options.
