The Online Scoring Network (OSN) is a proprietary software application that enables Raters to score examinees' written and spoken test responses online. Raters score these responses via the Internet from their homes or offices in accordance with ETS guidelines. On occasion, Raters will use the OSN to score responses at regional site locations.
The process that Raters will go through for each testing program includes:
- training via program-specific instruction provided either on a website or on paper
- certification via tests that prospective Raters must complete successfully in order to score for a particular program
- scheduling procedures for assigning certified Raters to scoring sessions based on the availability of Raters and on the volume of tests
- mentoring by ETS Scoring Leaders who work with Raters throughout each scoring session to help them score responses according to testing program standards
To certify and score using the ETS OSN program, prospective Raters must have computer equipment that meets the minimum hardware and software requirements.
