Our district has inclusion gifted services (I think enrichment for the whole class, like music or art) for K and 1 for 1 hour every other week. At the end of 1st all kids are tested. Those found gifted may be offered a place in magnet school. All gifted kids who don't go to the magnet school (and those suspected of being gifted - I think they test high but not quite high enough) are placed in "gifted cluster" classes. A gifted cluster class has up to 8 gifted and suspected gifted kids, and the rest of the class is average-performing and above. Those classes get gifted inclusion services 1 hour once a week. Nobody gets pulled out. I don't know if it's a good system or not. My ds goes to the magnet school, and I think it's been good for him overall.
