I may be an odd candidate for this proposal but I am a Middle School teacher in the U.S. I do not teach ESL but I have previously taught Middle School Spanish in my early days of teaching. I am not teaching this year, I am helping out with technology for this school year, but I have previously taught all Middle School subjects, including English. While I do not and have not taught ESL, for the past 5 years, I have worked with (and currently work with) multiple ESL students. Plus my position this school year would make me a prime candidate to recruit help from multiple students in testing your website/app.
