Help: Missing LENA Day Data

What to do when your LENA reports seem incomplete or show the wrong date.

Check your timing.

Has it been at least 4 hours since the Hub finished uploading the data to the cloud?

Remember the steps:

1. Processing devices takes about 30 minutes of hands-on time per room.
2. Uploading transferred files occurs automatically and takes 5-20 minutes per child.
3. After upload, the next steps are automated analysis and creation of graphs. This process can take a few hours.

Check for short recordings.

The minimum duration for a LENA Day is 2 hours.

If no child in the room meets the minimum duration, no report is generated for that date at all.

If an individual child's recording is too short but other children in the room meet the minimum duration, the short recording is omitted from the Room Report and Child Report. The Interaction Chart indicates that the child's recording was too short. 

In either case, basic information about the recording is displayed in the Recordings list for the child. To view each child's full list of recordings, including too-short recordings, click the Children tab, the child's name, and then the Recordings tab.

Check schedule, and check for hidden recordings.

If any child in the group contributed two LENA Days within a calendar week for any reason, the second LENA Day received is automatically hidden for the whole group.

View a child's full list of recordings by clicking the Children tab, the child's name, and then the Recordings tab. The account owner can correct the report(s) by unhiding intentional LENA Days (and hiding accidental ones, if needed).

Note: If LENA Days are also associated with the wrong room and/or the wrong child, contact LENA Support for help moving the data.

Check with teacher about attendance and participation.

If a child was absent, he or she will not have data.

Check in with the teacher for anything unusual that may have happened, such as:

• Used a different device for this child.
• Child refused to wear the vest, no recording started.
• Child arrived very late and they forgot to start the recording.
• Device would not turn on or start recording.

Check your LENA Hub.

Did all the transferred files finish uploading?

Remember: Computer must be on, laptop lid open, connected to Internet, not sleeping , and Windows user signed in until Hub shows 0 Uploading.

Open the LENA Hub where the devices were processed, and check for any files still uploading. Allow it to finish. The report will be ready 3-4 hours after uploading completes.

Note: Each file should upload in 20 minutes or less. Click here for problems uploading.

Check devices.

Occasionally, a device processing mistake leaves the data on the device. You may have accidentally:

• skipped one or more devices when connecting to Hub, because it wasn't with the others.
• disconnected devices that were still in Waiting status, not yet transferred.
• not noticed that LENA Hub didn't respond to one or more devices.

Turn on the device for the missing child and read its status screen to see if the data is still there. Remember:

Paused = Empty. Either you already transferred the data, or no recording was started. Paused with elapsed time = Contains a LENA Day. Connect to Hub to process. Memory Full = Contains a LENA Day. Connect to Hub to process. Any other message, or won't turn on = Problem that may have prevented recording and/or transfer. See device troubleshooting.

Check the child's previous LENA group.

A child's LENA Day is associated with the LENA Online group the child was in at the start of that day. If you moved the child – or opened the new group – after the recording was started, LENA Support can help you move the child's LENA Day to the current group.
