The data on CogMed is pretty much the same as it was 5 years ago, which is that the best research doesn't support its effectiveness. Now, if you can get the district to pay for it, I don't think there's any real harm in it, either, but it does still have a cost in time. Like most interventions with anecdotal support but without a solid evidence-basis, it is possible that there are specific people and circumstances out there for whom it would be helpful, but there isn't currently a reliable way for identifying which people those would be.
