Based on the Campus Green color and components (assuming they are original) that looks like a 1970 model. It appears to have the smallest 21" size frame available that year: Schwinn 1970 Diamond Jubilee -- Continental / Super Sport

You can check the hubs, crank and fork steerer tube for date codes. The hub stamps should be plainly visible however the crank and fork would need to be removed to see any codes on them.
