Spells at Ministry were intended for Defense

A lot of posts about what spells Harry and company used and why they 
seem to be simple spells learned early on.

I felt the same way initially. But, tjen decided to reread scene for 
PURPOSE of spells that Dumbledore's army were using. I had a 
revelation-supported by the name of the training itself-DADA-we 
are talking about DEFENSE.

So, really, Protego, Patronuses, Petrificus Totallus, Expelliarmus, 
Stupefy, Silencio and good old fashioned dueling are being used. 
True, the youngsters do not duel as well as the death eaters.  So, 
they have to rely on alot of ingenuity i.e.: reducing the shelves and 
spilling prophecies, floating brains, poking wands in eyes, etc.

Keep in mind that the majority of the dangerous and damaging spells 
would probably belong to the DARK ARTS. The true irony is 
that DA (Dumbledore's Army) will never (we hope) stoop to DA (dark 
arts). We see Harry attempt one unforgivable spell out of frustration 
toward Bella following Sirius' death-but he miserably fails-because 
he is not a Dark Arts practicioner (fortunately).

Even the Order members, including Dumbledore and several aurors do 
not resort to the Dark Arts. Their spells are defensive and 
restorative (Lupin's Finite) if needed. It is only the DEs we see 
sending jets of green light or curses of purple, and applying 
unforgivable curses. This is a critical distinction between the 
tactics of both sides as war approaches.

As for Harry and his proteges, they learned several new spells since 
3rd year (keep in mind Harry knew many from his one on one training  
with Lupin and his preparation for Triwizard tournament). 

Too, this year was a time for them to practice previously acquired 
spells, honing them and improving their accuracy. We still see that 
some (i.e. Neville) have an accuracy problem and do not always hit 
what they are want.  As we see, they still need further honing and 
practical experience, which is why I for one think DADA is more 
necessary now then before.  The student body must be prepared for the 
coming events.
