Mine is a Title One/??? teacher (she is supposed to work with the ELD teachers but I don't think she is a "real" ELD teacher). This year for me (I was 3rd grade, will be 2nd next year) she pulled 2 kids out and worked on their writing. She had 2 ELL's but a little over halfway through the year I switched it to 2 REALLY low English only students.
Then I had a Spanish Paraprofessional who when she was here pulled any number of students depending on who was there & what else was happening and she worked on basic grammar skills with them while I was doing Social Studies/Science or finishing math/LA.
If you want to know what I would want- the #1 thing would be a clearer understanding of what I should be looking for in terms of "is this an issue because the student speaks Spanish at home or is this an issue because the student doesn't get it?". I had quite a few Spanish only students who were REALLY high but would make some strange mistakes & I never knew why they did. The students could communicate with me perfectly & vice versa
