The COVID-19 Pandemic drastically changing all aspects of our world, and one of the most impacted areas is educational assessment and other types of assessment. Many organizations still delivered tests with methodologies from 50 years ago, such as putting 200 examinees in a large room with desks, paper exams, and a pencil. COVID-19 is forcing many organizations to pivot, which provides an opportunity to modernize assessments. But how can we maintain assessment security – and therefore validity – through these changes? Here are some suggestions, all of which can be easily implemented on ASC’s industry-leading assessment platforms. Get started by signing up for a free account at http://assess.ai.
True item banking with content access
A good assessment starts with good items. While learning management systems (LMSs) and other not-really-assessment platforms include some item authoring functionality, they usually don’t meet the basic requirements for real item banking. There are best practices regarding item banking that are standard at large-scale assessment organizations (e.g., US State Departments of Education_, but these are surprisingly rare for professional certification/licensure exams, universities, and other organizations. Here are some examples.
- Items are reusable (you don’t have to upload for each test where they are used)
- Item version tracking
- User edit tracking and audits
- Author content controls (Math teachers can only see Math items)
- Store metadata such as item response theory parameters and classical statistics
- Track item usage across tests
- Item review workflow
Role based access
All users should be limited by roles, such as Item Author, Item Review, Test Publisher, and Examinee Manager. So, for example, someone in charge of managing the roster of examinees/students might never see any test questions.
There are many ways you can analyze your test results to look for possible security/validity threats. Our SIFT software provides a free software platform to help you implement this modern methodology. You can evaluate collusion indices, which quantify how similar the responses are for any pair of examinees. You can evaluate response times, group performance, and roll-up statistics as well.
When tests are delivered online, you should have the option to randomize item order and also answer order. When printing to paper, there should be an option to randomize the order. But of course, you are much more limited in this respect when using paper.
Linear on the fly testing (LOFT)
LOFT will create a uniquely randomized test for each examinee. For example, you might have a pool of 300 items spread across 4 domains, and set each examinee will receive 100 items with 25 from each domain. This greatly increases security.
Computerized adaptive testing (CAT)
CAT takes the personalization even further, and adapts the difficulty of the exam and the number of items seen to each student, based on certain psychometric goals and algorithms. This makes the test extremely secure.
Want to ensure that the student can’t surf for answers, or take screenshots of items? You need a lockdown browser. ASC’s assessment platforms, Assess.ai and FastTest, both come with this out of the box and at no extra cost.
Examinee test codes
Want to make sure the right person takes the right exam? Generate unique one-time passwords to be given out by a proctor after identity verification. This is especially useful with remote proctoring; the student never receives any communication before the exam about how to get in, other than to start the virtual proctoring session. Once the proctor verifies the examinee identity, then they provide the unique one-time password.
Want an extra layer on the test kickoff procedure? After a student has their identity verified, and enters their code, then the proctor needs to also enter a different password that is unique to them on that day.
Want to prevent examinees from logging in early or late? Set up a specific time window, such as 9-12AM on Friday.
This level of proctoring is relatively inexpensive and scalable, and does a great job of validating the results of an individual examinee. However, it does nothing to protect the intellectual property of your exam questions. If an examinee steals all the questions, you won’t know until later. So, it is very useful for low or mid-stakes exams, but not as useful for high-stakes exams such as certification or licensure. Learn more about our remote proctoring options. I also recommend this blog post for an overview of the remote proctoring industry.
Live Online Proctoring
If you can’t do in-person test centers because of COVID, this is the next best option. Live proctors can check in the candidate, verify identity, and implement all the other things above. In addition, they can verify the examinee’s environment and stop the exam if they see the examinee stealing questions or other major issues. MonitorEDU is a great example of this.
