LENA Grow requires the use of hardware and software. The following are the requirements to be able to operate LENA Grow at a school, center, or family child care home.
LENA Grow App
Teachers use the LENA Grow app to access LENA data and complete app sessions. Each teacher has a LENA Grow account. Teachers may share a device. Required:
- Unique email address for each participating teacher
- Smartphone or tablet, ideally < 5 years old:
- iOS/iPadOS 16.6+
- Android 7.0+
- 2GB+ RAM, 150 MB available storage

LENA Online Technical Requirements
Site Managers, Coaches, and Program Managers configure sites and groups and access LENA data in this web application. Required:
- A computer running Google Chrome.
LENA Dock and Devices
LENA ships a dock and devices for each classroom. Docks are placed in the classroom to which they are assigned for use on each LENA Day. Required:
- Site must either be in range of a cellular network or have access to the site's Wi-Fi in order to process data.
- A standard 3-prong power outlet for the dock.
LENA Wi-Fi Connector App
A mobile app allows you to connect the LENA dock to your local Wi-Fi network if the built-in cellular network is not strong enough. Required for Wi-Fi connection and use:
- Smartphone or tablet:
- iOS/iPadOS 16.6 or later
- Android 7.0 or higher

Additional Recommendations
-
Color printer if printing paper reports from LENA Online
-
Ensure notifications are turned on for the LENA Grow app
- If a site has neither cellular nor Wi-Fi access, the dock may be kept offsite. Someone can bring devices to the site on the morning of the LENA Day, then retrieve them for processing offsite after.
