The ELI tests participants at the beginning and again at the end of the program for their oral English competency, using the SPEAK, a test of spoken English proficiency and the UDIA, a teaching test, which supplements the SPEAK by assessing overall language skills, cultural skills, questioning skills and basic teaching skills as the ITA teaches his/her subject to a group of students. Final testing determines participant readiness for instructional duties. Results of final testing will determine an ITA’s instructional duties.
