For my senior design project I will be designing an operational amplifier testing device.
The goal is that a student can plug in an Op Amp (741) and a screen will display the measured parameters of the op amp. The testing device should be able to display all of the parameters that can be found on the 741 data sheet. Then the display will (...)

The + input of IC1 is held at +12V
The - input of IC1 will not go higher than +12V, so there is a good change that IC1 output will be permanently high.
I would have put a potentiometer (maybe 100k Ohms) on the + input of IC1 to provide a variable reference voltage.
I am assuming that IC1 is a 741 op-amp or similar?

The lousy old 741 opamp design is 46 years old. It works poorly above 9kHz.
Audio opamps work well up to 100kHz and higher. There are many of them available in The West.

A lousy old 741 opamp design is 46 years old. The opamp has such poor specifications that it should be buried.
An opamp can be used in thousands of circuits. Look at OPAMP CIRCUITS in Google Images (but it has no oscillators).
