We do have a parent from Venezula that teaches Spanish to a couple of classes. I think that is so awesome. I wished she could do more. We are a VERY non-diverse, very small county, people like her are hard to come by, we do now have a Mexican Restruant that opened in the fall and she had the owner to come over and they had several different dishes.

Is it politically correct to ask if parents are from a different part of the world? I've led a sheltered life, I would hate to offend anyone.

We don't have a formal program but here are some things that are usually available -

1 Band and orchestra demonstrations. Students get to see and hear instruments before joining a 5/6 grade band.
2 Local high school choirs, bands and orchestra perform for the kids. The show choirs will come to the school frequently.
3 We have art shows and performances every semester from each grade. Kindergarten does one for Chinese New Year.
4 There are theatrical groups that come to the school.
5 The library uses some funds from the book sale to host a visiting author each year. The author talks about writing and does a demonstration. They get really interesting and entertaining people that encourage the kids to write and illustrate stories and not expect them to be perfect.
6 We do Junior Great Books book club. The only costs are the books that the students buy.
7 Destination Imagination is great. Sometimes it's an art project, a play or making a clock. It depends on the challenge they choose. The point is to have the kids work together to produce something. But you could stear it towards arts and humanities.
8 Language classes are great. (I wish someone would let me teach Portuguese or Italian.)
9 Literacy night is a biggy. Each parent attends three mini classes to help their kids learn and enjoy to read and write. We have door prizes, fun stuff for kids while the parents are in class and about 20 classes lasting about 20-25 minutes geared for certain skills and grade levels.
10 Pizza Hut's Book it program runs 6 months and is a great incentive to read.
11 We have Race to Read after the Pizza Hut program is over. There are tally sheets for logging reading and prizes for each time you finish a "lap" (4 hours for k-2, 8 hours for 3-6) the final prize for 4 laps in 5-6 weeks is tickets for the student and an adult to Banimere speedway. The top readers get their names up on the marquee that day too. For the kick off, we have race cars come for the kids to look at. (This is really good. My son will read for hours to stay a "lap" ahead of his friends.)

Also -
If you contact community theatres, I bet you'd find one that would like a captive audience.
Check out what the other schools are doing in theater because my high school did Charlotte's Web for the elementary one year. That school always did a school wide preview before opening night.

Ask around. I just found a parent who had been a teacher in Kenya. She was a guest speaker for us in our book club. She brought in beaded necklaces and a zebra pelt.
You probably have tons of resources but don't know it. It's surprizing what there is available.

I was wondering if anyone school's has a program for Arts and Humnaities and how it works. Also does your PTO support it in anyway. A school not to far from us has one with a Title I teacher and they have raised their test scores 25 pts in this subject. I would love to see one here but our Governor has froze the budget so I doubt there will be any new programs added from our BOE, also next year we will be loosing our 5th grade to the "5/6 Center" and we have a new middle school and partially new high school plus a new superintendant coming in (what an eventful year we will have!).
