Test of English Language Learning (TELL)
When a student first comes to a school, they often know when English isn't their first language. What they don't know is how far from English fluency they are. The challenge for this digital assessment – Test of English Language Learning (TELL) – was to design the experience in such a way that the student can complete the assessment even if they don't interact with the screen or speak at all.
I was the UX/UI Designer while the first version of TELL – Test of English Language Learning. Designed to accurately assess the English speaking, listening, reading, and writing skills of K-12 students whose first language is not English. The results of this assessment help schools and teacher places students in various levels of English classes. My role was over the user experience design, user interface design, and asset/media design. I worked with psychometricians, content engineers, design vendors, engineers, and marketing.
A Unique Approach to Diagnostic Testing
TELL (Test of English Language Learning) is the first tablet-based language proficiency test with speech recognition. The iPad app was developed with high-quality graphics, an intuitive and simple user interface, and immediate feedback capabilities.

Easing Students In
Because our users are not proficient English speakers, we paid careful attention to introduce the test in an approachable and non-intimidating way. All unnecessary and distracting elements were eliminated and the interface was made to be friendly and easy to follow.

Instructional Videos
Instructional videos were developed for every question type that showed a student answering the question. This was crucial for helping non-English speakers navigate the different response formats.

Speak Your Answer
Language skills are tested using a variety of methods. This allows the student to demonstrate their ability in a way that could never be done with traditional pencil and paper tests. In this case, students can speak their answer to the app after an image or video prompt.

Write Your Answer
Language skills are tested using a variety of methods. In this case, students use their finger to write their answer on the familiar D'Nealian lines.

Type Your Answer
Language skills are also dependent on the student's age. In this case, the older students have the opportunity to type their answer. The youngest students, no matter their language proficiency, would not be able to type their answer. This adaptability of question format more accurately tests the students' skills.

Touch Your Answer
In our usability tests, we found that some low-proficiency students could not type or speak their answer, but excelled at touching a picture with their correct response. We incorporated fun, casual, and colorful images that show scenes from everyday life. For instance, a student may not know how to write the word giraffe, but if asked to “touch the giraffe" they could.

Because our students are not native English speakers, we included only the simplest and easiest to understand language.
