I have a question regarding the two demographic groups for the bonus prizes:
Two Bonus Prizes of $500,000 each will be given to the teams that can demonstrate the greatest literacy gains of their field-test participants over 12 months in one of the two demographic groups as measured by the CASAS pre- and post-tests. The two groups are:
English Language Speakers (ELS) – This target demographic represents native speakers of English, aged 18–64, whose literacy skills are at or below the NRS EFL Beginning Basic Education level, with a pre-test CASAS score of 210 or below.
English Language Learners (ELL) – This target demographic represents non-native speakers of English, aged 18–64, whose literacy skills are at or below the NRS EFL Low Intermediate ESL level, with a pre-test CASAS score of 210 or below.
Is it known where the non-native speakers in the ELL target demographic are from? Are they coming from the same country, or is there a mixture of several nationalities? If mixture, what are the most common native languages amongst this demographic?
Such information would be useful in order to adapt the solution to different base languages, as people with different nationalities tend to have different problems when learning English.
