Administering K-D Test

King-Devick Test Setup:

Before a Student can begin practicing they will have to establish a starting speed by taking a King-Devick Test (K-D Test).

Administrator: Sit next to the Student (side-by-side) for test administration. Mouse and keyboard control is for Administrators only during testing. Have a scoresheet and pen/pencil ready.

Tip:Try laminating the scoresheets and reuse them for testing.
Student: The Student should sit with good posture, at an arm’s length from the screen, with eyes level at the top of the screen. During testing, the Student should hold the head still and move the eyes only, without using a finger to follow along, while calling out the numbers.

Scoring: The King-Devick Test is scored on age, speed and accuracy. Timing will automatically begin after the administrator clicks Next on the Demonstration Card. The Student should immediately begin reading numbers aloud on the test cards. After the Student calls out the last number on each test card, click Next to pause timing and proceed to a break card. Repeat the procedure for Test Cards II and III. The administrator will record errors for each Test Card on the scoresheet. An error is recorded for each omission, addition, substitution, and transposition. If a Student skips a line, 5 errors (omissions) should be recorded.

Tip: If a Student makes an error and quickly corrects it, no error is recorded.
  1. Select the Student listed as Awaiting King-Devick Test in from the left column. In the Student's page, click the blue button labeled King-Devick Test.

  6. You will be directed to the King-Devick Demonstration Card. Use this card as practice and explain to the Student how to read aloud the numbers from left to right as quickly as they can while trying not to make errors. When the Student understands the task at hand, click Next and proceed to Test Card I. The Test has begun, and the Student should immediately begin calling out numbers.

  8. Once the Student calls out the last digit on Test Card I, quickly click Next to proceed to a break card. Timing is paused on all break cards. Once the Student calls out the last digit on Test Card I, quickly click Next to proceed to a break card. Timing is paused on all break cards.
  9. Tip:If Test Card II was very difficult for the Student or excessive errors were made, the K-D Test can be stopped after Test Card II.

  10. After the Student completes Test Card III, the administrator tallies any errors and enters the total errors on the Results page. Enter tester’s initials and any optional comments. Click Confirm and results will be automatically compared to age-matched normative data. The Student is ready to begin practicing.

Practicing in RAP

What to do While Practicing

  • Posture: The Student sits with good posture, approximately arm’s length from the screen, with the eyes level at the top of the screen.
  • Head Position: During practice, the Student should hold the head still and move the eyes only.
  • Rapid Number Naming: Once practice begins, the Student says each number out loud, left-to-right, top-to-bottom as quickly and accurately as possible.
  • Adjusting Practice Speed: The goal is to achieve the fastest speed (numbers per minute) with no errors. It may take a few trials to find the ideal practice speed. If the Student is having difficulty keeping up or has excessive errors, adjust to a slower speed. If the Student is able to see and say all numbers presented without difficulty, increase the speed by 5 numbers per minute. 100% accuracy should be achieved for three practice rounds, or nine Practice Cards, before increasing the speed.
  1. Once a Student has completed their King-Devick Test, they are now ready to begin practicing. The speedometer is automatically adjusted to the recommended starting speed based on K-D Test performance. To manually adjust your Student's practice speed, click faster or slower on the speedometer, or click and drag the speedometer needle. Once the desired speed is selected, click the Practice button.

The speedometer is automatically adjusted to the recommended starting speed based on K-D Test performance. To manually adjust your Student's practice speed, click faster or slower on the speedometer, or click and drag the speedometer needle. Once the desired speed is selected, click the Practice button.

    A note regarding Image Selection:
    The Recovery Acceleration Program includes a feature called Image Selection that allows subjects to select various target images rather than numbers to call out. The alternative options are colors, shapes, or farm animals. This feature cannot be used in conjunction with Practice Accuracy Checking, as that is only able to be used with number naming. The Subject's speed may vary depending on the target images they decide to use.

  8. After a completing 3 practice cards or 1 practice round, the Student will be prompted to practice again at the same speed, faster, slower or finish their practice session. The administrator selects the desired option, and the Student resumes or finishes practice for the session. Click Continue to proceed.

Practice Accuracy Check

The Practice Accuracy Check is an optional feature that uses your device microphone and speech technology to provide automatic accuracy estimates during your Student’s K-D RAP Practice.



The K-D RAP Administrator checks the Practice Accuracy Check box in the Student’s profile to enable it.






Practice Accuracy Check can be toggled ON or OFF depending for a given practice under the speedometer.

Goals and Rewards

Once a Student has established their starting speed, you can set goals to help guide their practice by editing the Student. Consistency is the most important thing when going through RAP, so it is generally recommended to set goals of shorter intervals more frequently throughout the week.

Recommended Practice Protocol

  • 5-minute sessions twice per day, 6 days per week
  • 10-minute sessions 6 days per week
  • 15-minute sessions 4 days per week

Practicing Ideas

Consider adding the following exercises to increase the difficulty of the learning task and capture attention with new training activities. The Student is to continue reading the number targets presented.

  • Techniques to increase attention and difficulty:
    • Number of the day: Pick a ‘number of the day’ between 0 and 9. Have the Student clap or snap any time he or she says the ‘number of the day’. To increase the difficulty, select two ‘numbers of the day’, and have the Student clap at one number and snap at the other number. For example, the Student claps when calling out the number 5 and snaps for 2.
    • Number memory: Pick a number between 0 and 9. Have the Student remember how many of that given number she or he saw in a test card. If this memory task is too difficult, have the Student keep track of how many of the given numbers was seen by keeping track using finger-counting.
    • Number Replacement: Replace another word with the ‘number of the day’. For example, have the Student say her or his favorite food for the number ‘0’.
    • Whisper Number: The Student calls out all numbers in a normal voice volume except one specified number, which the Student whispers.
    • Mystery Speed: After practicing at length at the Student’s current speed, change things up, by picking a mystery speed for the Student to try. Have the Student close his or her eyes as to not see the ‘mystery speed’, then have the Student open their eyes to begin once clicking the Practice button. To increase the difficulty, have the Student guess what the mystery speed is.
    • Team Number: Pick a number, have the Student give the administrator a ‘high five’ when the Student identifies or calls out a certain number.
