UPDATE: What’s New, Ended, Ending and Coming

The following is an overview of upcoming changes to the hardware and software supported for DRC INSIGHT and/or COS Service Devices.

Operating System Support

What’s New

Ubuntu 20.04 LTS

Ubuntu 20.04 LTS was released at the end of April 2020. DRC has added it to the list of Best Effort Supported operating systems and anticipates moving it to Fully Supported in July or August 2020.

What’s Ended

macOS 10.12

Apple dropped support of macOS 10.12 in 2019. This resulted in DRC moving support for macOS 10.12 to End of Support.

What’s Ending

Windows 7 and Windows Server 2008

Microsoft ended support for Windows 7, as well as support for Windows Server 2008, in January of 2020. DRC continued to support both Windows 7 software and Windows Server 2008 software throughout the 2019–2020 school year.

The current versions of DRC’s software have not been tested or verified on Windows 7 or Windows Server 2008, therefore DRC will provide Best Effort Support for these OS versions at this time. DRC plans to move these operating system versions to End of Support at the end of September 2020.

What’s Coming

Windows 10X

DRC anticipates the launch of Windows 10X in the fall of 2020. Initially this was a unique version of Windows designed specifically for dual-screen devices. In early May 2020, Microsoft announced their intentions to pivot and focus toward delivering Windows 10X on single-screen devices first and were postponing their plans for dual-screen devices. Microsoft has not yet provided a release date for Windows 10X.

Following DRC’s Operating System Support Policy, current plans are to support this operating system on single-screen devices. DRC currently does not have plans to support dual-screen devices when they are available.

DRC will continue to monitor Microsoft’s plans for releasing Windows 10X and evaluate support as the operating system and device scope evolves.

Windows 10 Fall Release

DRC anticipates Microsoft's semi-annual release with feature update to Windows in September of 2020.  Support of this release will follow DRC’s Operating System Support Policy. It is not known yet whether this release will require an update to the DRC INSIGHT Secure Browser for Windows and/or the DRC INSIGHT Secure App for Windows 10 in S mode.

macOS 10.13

DRC anticipates Apple will drop support of macOS 10.13 in September with the introduction of macOS 10.16. This would result in DRC moving support for macOS 10.13 to Best Effort Support in September 2020 and to End of Support in November 2020.

macOS 10.16

DRC anticipates Apple’s annual release of an upgrade to macOS, likely called macOS 10.16, in the fall of 2020. Support for this release will follow DRC’s Operating System Support Policy. It is not known yet whether this release will require an update to the DRC INSIGHT Secure Browser for macOS.

iOS 12

Anticipate Apple will drop support of iOS 12 in September with the introduction of iOS 14 and iPadOS 14. This would result in DRC moving support for iOS 12 to Best Effort Support in September 2020 and to End of Support in November 2020.

iPadOS 14

DRC anticipates Apple’s annual release of an upgrade to iPadOS, likely called iPadOS 14, in the fall of 2020. Support for this release will follow DRC’s Operating System Support Policy. It is not known yet whether this release will require an update to the DRC INSIGHT Secure App for iPad.

 

Device Support

What’s New

No new device support has been added.

What’s Ended

No recent end of life devices.

What’s Ending

iPad Air devices

The iPad Air device supports only iOS 12.x. DRC anticipates with the launch of iOS 14 in the fall Apple will drop support for iOS 12.x resulting in this device no longer being supported by Apple and therefore DRC.

What’s Coming

No new device support anticipated.

UPDATE: New or Changing DRC Technology

The following is an overview of upcoming planned changes to DRC software and technology components.

64-bit DRC INSIGHT Secure Browser for Windows Now Available

The DRC INSIGHT Secure Browser for Windows installer has been updated to 64-bit. This updated version is available for download from the DRC INSIGHT Portal > General Information > Downloads page. If the 32-bit installer is needed, please contact DRC Customer Service.

If an existing testing device has the 32-bit version installed and auto update is enabled, it will automatically update to the updated 32-bit version. To convert an existing testing device with the 32-bit version to the 64-bit version, the 32-bit version will need to be uninstalled and the 64-bit version would then need to be installed on the testing device.

Testing Device and COS Service Device CPU Benchmark Ratings

DRC recently enhanced and simplified the processor specification for COS Service Devices and for testing devices. DRC now expresses the specifications in terms of a Central Processing Unit (CPU) benchmark rating that assesses overall processor performance. Prior to this the CPU specifications listed a single Intel processor with a comment of “or equivalent” without any context of that processor’s performance.

The CPU benchmark ratings used for the CPU specifications are created by an independent third party, PassMark Software, that uses special software to test and gauge CPU performance benchmarks in a standardized way. The resulting ratings make it easier to understand differences in CPU performance and to set device processing standards.

It is important to note that the device specifications for test devices and COS Service Devices have not changed or increased through the use of CPU benchmark rating. The processors used in 2019-20 System Requirements were used to determine the CPU benchmark ratings in this document. DRC has not changed the system specification for either the testing devices or the COS Service Devices in the 2020-21 academic year.

Minimum vs. Recommended

Throughout this document, the Minimum level of requirements represents a low compliance threshold. For the best student testing experience, DRC advises using the Recommended level or above. The Recommended level is required for testing with accommodations such as Human Voice Audio (HVA), Text-To-Speech (TTS), and Video Sign Language (VSL).

DRC INSIGHT Testing Device Additional Notes

Wi-Fi Recommendations

When testing using a wireless network, DRC recommends a wireless site survey be completed to ensure that there is enough, unobstructed wireless coverage in testing areas. This survey should address coverage and verify that the anticipated number of testers can take the test in the same area of the building at one time (device density).

The survey should also verify there is adequate Local Area Network (LAN), Wide Area Network (WAN), and Internet bandwidth to support the number of testers expected to be testing at the same time. Also account for other traffic in the building that will be occurring at the time of testing.

Windows and Chrome OS Touch-Screen Devices

Device manufacturers use different methods to implement touch-enabled screens for their devices. DRC verifies DRC INSIGHT on manufacturers' touch devices commonly used in educational settings.

Neverware CloudReady and DRC INSIGHT—PCs and MACs to Chromebooks

CloudReady from Neverware is a reduced-feature Chrome operating system that runs on older PC and MAC hardware with limited resources. DRC and Neverware have tested CloudReady and have confirmed that it meets the requirements for testing. Sites will need to partner with Neverware for this solution.

Neverware and DRC offer full support for CloudReady for testing with DRC INSIGHT on testing devices that meet the DRC Chrome OS system requirements. Sites using CloudReady should follow the Chrome OS installation instructions.

Tablet/Netbook/Chrome Devices

Because tablet/Netbook/Chrome devices are not easily configurable for additional memory and storage (disk space) upgrades, DRC recommends that these devices be streamlined for the DRC INSIGHT Secure App.

DRC recommends all applications and features that are unnecessary for testing be removed, turned off, or disabled to ensure that the maximum amount of device memory is available for testing. This includes services such as Bluetooth (unless a Bluetooth keyboard or mouse is needed), GPS, and power saving modes that reduce performance to maximize battery life. DRC also recommends rebooting these devices before testing. These activities help free available memory. Devices that lack enough memory may experience issues.

IPA Software

Intelligent personal assistant (IPA) software, such as Siri for iOS and macOS, or Cortana for Windows 10, should be disabled during testing for the appropriate devices. In some cases, this functionality can be disabled automatically using administrator controls such as Mobile Device Management (MDM) software.

If IPA software is not disabled, the testing site is responsible for ensuring the security and integrity of the test by actively monitoring that students are not using this capability during the test.

Microsoft Teams App

The Microsoft Teams App should be disabled during testing for the appropriate devices. This functionality can be disabled by managing the deployment/installation of the testing device’s Microsoft suite or refer to the “Use Group Policy to prevent Microsoft Teams from starting automatically after installation” section in the “Deploy Microsoft Teams with Microsoft 365 Apps” guide to learn more about how Microsoft recommends disabling Microsoft Teams.

If the Microsoft Teams App is not disabled, the testing site is responsible for ensuring the security and integrity of the test by actively monitoring that students are not using this capability during the test.

Automatic Operating System Updates and Other Background Processes

Some operating system vendors have policies where updates are automatically applied in the background. Update processes running in the background on testing devices consume CPU and memory and can affect the testing experience. For example, audio playback may be choppy and Speaking test responses may be distorted. To avoid this situation, verify that no background processes are running on testing devices during testing. Also, if a testing device is set to accept updates automatically, verify that it has the most current DRC-supported version already installed before the test session starts.

Accommodations

Tests with the Text-to-Speech (TTS), Human Voice Audio (HVA) or Video Sign Language (VSL) accommodations are required to be administered with a COS Service Device.

 

COS Service Device Requirements

Base Hardware Requirements

These base hardware requirements apply to all device types and operating systems.

·       Processor

o   CPU benchmark rating of 3000 or higher*

·       Available Memory

o   4 GB RAM or higher

·       Available Disk Space          

o   Minimum – 10 GB

o   Recommended – 20 GB or more

·       Network

o   A COS Service Device should be connected to the network through a wired connection.

Operating System Requirements

·       COS Service Device software is supported on the following operating systems:

o   64-bit Windows

o   64-bit macOS

o   64-bit Linux

·       COS Service Device software cannot be installed on an iOS, iPadOS, or Chrome OS device.
Note: iOS, iPadOS, and Chrome OS testing devices that have the DRC INSIGHT Secure App installed on them can be associated with any COS Service Device, regardless of its operating system. For example, an iPad or Chromebook testing device can connect to a Windows, Mac, or Linux COS Service Device.

Examples of COS Service Device Configurations

The following table lists examples of device processor and memory configurations for a COS Service Device to support various numbers of concurrent testers.

Note that testing sites are not limited to these configurations—they are listed to provide guidance regarding the scalability of COS Service Devices.

The table also lists the available shared network bandwidth required based on the number of concurrent testers. Shared bandwidth includes the Local Area Network (LAN), Wide Area Network (WAN), and Internet Service Provider (ISP) bandwidth. The bandwidth for each network segment should meet or exceed the minimum bandwidth listed in the last column of the table.

Shared bandwidth does not include the minimum bandwidth from the testing device to the network because that bandwidth is not shared by other testing devices. The minimum bandwidth from the testing device to the network is about 3-5 Mbps.

DRC’s Device Support Policy

Device Categories

DRC’s approach is to support our software on the devices most commonly used in the classroom. DRC’s device support policy for these devices considers three factors:

1.       Does the device’s specification meet DRC’s system requirements?

2.       Is the device running a DRC supported operating system version?

3.       Does the vendor support the device? (This question mainly applies to iPads and Chrome OS devices.)

When the answer to all these questions are yes, DRC will provide Full Support for the device. In other words, Full Support is provided for DRC software on vendor-supported devices that meet DRC’s device requirements and that are running under a supported operating system.

When a vendor ends support for a device, the device will no longer receive necessary security and functionality upgrades. This can compromise DRC’s ability to create a secure testing environment and may impact DRC’s software ability to function properly if the device does not support functionality DRC software requires. After the vendor ends support, DRC will provide Best Effort Support for a short period before also ending support.

Currently, vendor device support affects mainly Apple’s iPad devices and devices running Google’s Chrome OS.

Apple iPad Devices

When an Apple iPad model no longer has an Apple supported operating system version these devices are considered unsupported by Apple. Because Apple no longer supports the device, DRC is unable to offer support and recommends these iPad devices not be used for DRC INSIGHT online testing.

Google Chrome OS Devices

Each Google Chrome OS device has an Auto Update Expiration (AUE) date. Before reaching this date, the device automatically receives new software updates from Google. As Google’s Auto Update policy for Chrome OS devices states,

Chrome devices receive automatic updates regularly that enhance both the device itself and the software on the device. …However, end-to-end updates for all our devices to ensure the highest levels of security requires dependencies on many third-party hardware and software providers so we cannot indefinitely ensure that older Chrome devices will receive updates to enable new OS and browser features.

Google bases Chrome OS device’s AUE date on the model’s first production date, not the date the device was purchased. This is typically 5-6 years after the model’s first production release. When a device reaches its AUE date, Google considers the device obsolete, software updates from Google are no longer guaranteed, the device may not receive necessary security and functionality upgrades, and Google suspends the ability to manage it using the Google Management Console.

To determine the AUE date for a Chrome device, use the following link to Google’s Auto Update policy and the list of Chrome devices with their AUE dates: support.google.com/chrome/a/answer/6220366.

DRC will offer Best Effort Support for unmanaged Chrome devices (the DRC INSIGHT Secure Chrome App was manually installed) that meet the system device and supported operating system requirements.

Even if the device still has a supported version of Chrome OS, DRC recommends replacing any Chrome devices that have reached or will reach their AUE date within the school year.


DRC’s Operating System Support Policy

When a software vendor ends support for an operating system (or level), they discontinue free security updates for that software. This can present large and immediate security and support risks to the software’s users and potentially compromise DRC’s ability to create a secure testing environment. As a result, DRC strongly recommends that all clients use fully supported versions of operating systems.

Support Timeline

Graphic showing support timeline. 
Phase 1: Best Effort Support. 
Phase 2: Fully Supported. 
Phase 3: Best Effort Support. 
Phase 4: End of Support.

To accomplish the dual goals of minimizing security risks to DRC clients while making necessary software changes, DRC has established a multi-phase support timeline for the transition from an unsupported operating system or level to a supported operating system or level.

Note: DRC assumes no responsibility or liability for software transition processes at testing sites.

Phases 1 and 3: Best Effort Support

The DRC Support team will help troubleshoot issues reported concerning the operating system or level and DRC software applications as best we can, but DRC cannot guarantee a resolution.

If a problem is uncovered, DRC Support will report the issue to DRC Development. Again, we cannot guarantee a fix, software update, or resolution timeline for software fixes or updates. If DRC determines that an issue is related to a client’s network, hardware, or thirdparty software, the client must obtain support directly from the software vendor or the hardware manufacturer.

Best Effort Support occurs at both ends of the software lifecycle.

·       Phase 1: After DRC software testing begins and before the software is fully supported by DRC. DRC offers Best Effort Support for any new version of a supported operating system (OS) product within 30 days of public availability of the OS product version, or by the next planned common or client-specific release date of the DRC application, whichever duration is greater.

·       Phase 3: After the software is no longer supported by the vendor and before the end of DRC support. Once the OS product version has reached the end of vendor support, DRC offers Best Effort Support until the next planned common or client-specific release date of the DRC application, at which point it is restricted from use unless DRC chooses to extend support.

Phase 2: Fully Supported

Operating system versions on the DRC Fully Supported operating system list have been verified by DRC. DRC supports major versions that are publicly supported by the product vendor and minor versions of the product when DRC deems necessary. Any new version of a supported OS product will be Fully Supported by all DRC applications within 90 days of public availability of the version of the OS product, or by the next planned common or client-specific release date of the DRC application, whichever duration is greater.

Phase 4: End of Support

The next release of DRC software applications will not work with the unsupported operating system or level. It is restricted from use.
