Avant STAMP 4S Frequently Asked Questions

Avant STAMP 4S Guides

What is Avant STAMP 4S?

Avant STAMP (STAndards-based Measurement of Proficiency) 4S determines language proficiency in 4 domains (Reading, Writing, Listening and Speaking,) for grades 7-16. Avant STAMP 4S is web-based and computer-adaptive, with real-world questions on topics selected to be level-appropriate based on research into topics taught at each level. The questions engage learners, and because Avant STAMP 4S is adaptive, students are able to demonstrate their own actual proficiency level without any pre-set upper limits. Avant STAMP was originally developed by the Center for Applied Second Language Studies, a National Foreign Language Resource Center at the University of Oregon and funded by the US Department of Education. Avant STAMP 4S has been validated by field testing and expert panels. It is a secure test that requires a proctor during administration.

What is computer adaptive testing?

Avant STAMP 4S is computer-adaptive, meaning that the level of question difficulty that a student is presented with is based on the number of correct answers they have logged so far in the assessment. The testing engine automatically adapts to each student's level, up or down, as the test progresses. In addition, prompts for the productive skills (Writing and Speaking) are based on the proficiency level attained for the corresponding receptive skills (Reading and Listening). This approach was pioneered at Avant Assessment, the first company to develop commercial-grade, multi-stage, computer-adaptive tests for language learning, beginning in 2001.

Who uses Avant STAMP 4S?

  • Individual Reports - Individual reports show the Reading, Writing, Listening and Speaking levels attained on the Avant STAMP 4S for each test taker.
  • Line Item Summary Download - The line item summary download creates a Microsoft Excel file that includes student profile information along with the individual's test results and other test-taking data.
  • Summary Chart Download - If you prefer to create a different style of chart or graph, the summary chart download makes it easy to create a Microsoft Excel file with the information from the summary charts.

What are the System requirements?

Please see our Assessment Technology Guide for overall system requirements and browser capabilities.

What are the headphone requirements?

We strongly recommend using USB style headphones that completely cover the ears, blocking out much of the surrounding sound, with built-in microphones. Smaller earbuds or foam headsets that sit on top of the ear will not produce the best results in terms of sound quality.

Please see our Headset Guide for further information.

How are writing samples submitted for languages with accents and special characters?

All of Avant's tests include a Writing section in which learners will need to provide typed writing samples. The method for inputting the language sample may differ, depending on the target language for the test.

Please see our Writing Guide for language-specific directions.
