Their AI assessment for english language profficiency resulted in assessing me - a native english speaker - as "insufficient". On Septmeber 27, 22 I asked for re-assessment or explanation. I got a response on December 19, 22 - three months later, that they would "look into it". In the end their response was this: "Please see the findings of the manual review done on your recording by our assessment partner: "In reviewing this case, the user appears to be a fluent or native English speaker, however, their responses on a number of items did not mirror the prompt closely enough to merit a higher score. This is often due to native speakers not giving their full attention to the prompt assuming that they will score well without paying close attention." We know that your time invested in this process is valuable and encourage you to consider reapplying and taking the test after six months." In short - DO NOT WASTE YOUR TIME with Crossover.
