Alister Doyle, I work at Noodle.
Unfortunately Lou Henry does not have a Pre-K program anymore. There was a program some years ago but it has since been closed apparently. Several Waterloo Community Schools do have Pre-Schools though, which you can see here.
For more information you can also contact either Tri-County Head Start or Charletta Sudduth, who is in charge of the Waterloo Schools Pre-Schools. Her phone number is 319-433-2920. Sorry for the confusion but I hope you find what you're looking for!
