From CDP output I can see that there are many more switches in the network. If need help you will have to give a network diagram. It will be quick to solve problem with a diagram. Also, configuration output from all switches will be required. You can PM me.

If you do not have network diagram you will have to post the output from all switches :
1. Show ip route.
2. Show cdp neighbor
3. Configuration of all switches
4. Ports where the server is connected
5. Port where access point is connected
I will be able to draw a diagram based on that. After a clear picture I will be able to tell the configuration problems.

2960 is layer 2 switch. Show ip route may not work on that. If its is a layer 2 switch then the command interface vlan 10 and then ip address does not have any effect. On all layer 2 switches you just need the following command:
1. Swithport mode access
2. Switchport access vlan 10 or 20
And then on any port connect the access point. Inter VLAN routing will happen through layer 3 switch (3560). It is absolutely not neccessary to give command like:
1. Interface VLAN 10, ip address 172.16.10.2 255.255.252.0
2. Interface Vlan 20, ip address 172.16.20.2 255.255.252.0
3. Interface VLAN 50, ip address 192.168.0.7 255.255.255.0
The above three commands is only neccessary on Layer 3 switch. Your configuration on layer 2 switch (2960) does not have any effect.

1. Check the ip address of the ethernet card and wireless card. From the ip address you will be able to tell which VLAN they are joining. Check this for both student and teacher laptop. The wireless card should get ip address from their respective VLAN. A teacher laptop wireless card should get ip address from 172.16.8.0/22 network and a student laptop wireless card should get ip address from 172.16.20.0/22 network. Based on the ip address you will be able to tell if student is joining VALN 20 and teacher is joining VLAN 10. Check this information by moving the laptops around the school. What method have you utilised to make sure the student joins vlan 20 and teacher joins vlan 10 ?
2. On all switch check vlan database by using command : show vlan. All the switches should have identical vlan information. If not create vlans: 10, 20, 222 on all switches. For consistent VLAN database on all switches you can use VTP or you can create this manually.

I notice vlan1 ( is this still the default vlan ) is getting DHCP? unlikly to be a cause,
I also agree with sultan that you don't need ip's on the L2 switch vlans
you also seem to have eigrp on the 3560? is there a reason for that?

Have you added the new subnets you created to Active Directory Sites and Services? This will cause issues similar to what you're experiencing.

Don't you need to set the ip helper-address on the VLANs?

It is set.
