She didn't really answer your question, did she?
Suggest that you respond with;
1. I'm sorry that my question was unclear-- "How, exactly, can {DD} demonstrate her existing mastery of the required curriculum?" Realize that this might take several sessions-- offer to do what you can to minimize the impact on her as a teacher so that she doesn't think you're asking her to spend two afternoons one-on-one with just your child, going through the entire year's spelling textbook.
2. In addition to that question-- "what exactly is required for students in your classroom to demonstrate "mastery" within this spelling curriculum?" (that way she can't pull a stunt like stating that your DD has to do it like all the other kids in her class since she missed two words from December's slated spelling lists-- if a particlar level of proficiency is okay for other 4th graders AFTER instruction, then it needs to be okay from YOUR child before instruction, kwim?)
Yes, bring your spreadsheet from last year.
