Yes, we have 3 days advance notice in plan for class parties. For birthdays, food brought in by school start time day of celebration (but all are PLANNED celebrations with dates on a calendar communicated to teacher and parents at beginning of year and confirmed each month). Allergy parent comes to check labels in AM. If the food is not on suggested treat list, and not safe, it is not served. Nurse takes responsibility for calling parent, explaining they did not follow guidelines for the class, and they need to provide a food that adheres to guidelines if they want it served.
Right, go with "3 school days" (be clear, not "business days") or something like that..otherwise "48hr notice" will occur over a weekend and give you no notice.
This is a standard procedure and in many 504 Plans. Tell the Sp Ed Director that you have reviewed sample plans and this is STANDARD.
If you are not reachable 1hr before or 5 min before when a mom shows up with a birthday treat, that is not going to work. You must be given time to read the label, and/or make alternate plans (ie, if 504 Plan requires inclusive treats and the treat is not safe, gives time to change it; if you need to provide the treat, this will give you time to arrange a similar treat). Also, you may need to call a manufacturer to determine if a food is safe.
Again, if it's too much work for them, non food celebrations are inclusive, not risky, reduce planning, and take less time for everyone, allowing nurse to focus her job and teacher to focus on education in the classroom, not messy treats.
If that is not do-able, then I'm sure they can simplify the process with NON FOOD EVENTS. There should only be a couple class parties per year. They know the dates, so plenty of time for safe planning. For birthdays/other events, these are unnecessary and most schools are no longer doing them due to safety and inclusion concerns.
