:Here are some POV issues that still seem to need to be changed: 
 :* "Sachse has a high reputation on extra-curricular activities." - high reputation is an opinion, but also unclear. It may be better to change this entirely rather than just attribute the opinion. 
 :* "make the school's presence felt statewide and nationally" - any act of feeling is an opinion and should be attributed.  I'd recommend instead saying that the programs have been recognized state- and nation-wide, and adding citations to state- or national-level recognition for each of the programs. 
 :* "this past year." - not POV, but it's best to always state the exact time period.  What if nobody edits this and it still says "this past year" in 4 years? 
 :* "in many competitions" - don't use ambiguous words like "many", "some", "few", "a multitude", etc. Find out how many and use exact numbers. "At least three" or specifying no number at all and just talking about the competitions would both be better. 
 :* "other strong band programs" - "strong" is an opinion word, I'd suggest considering ways to rephrase or look for a citation. 
 :* "The band has also produced many outstanding soloists, including several all-state performers." - "many" and "outstanding" should be changed.  Just state the facts: If there are 8, then say "Eight of the band's 2007 members were selected for the Texas All-State Band". 
 :* "The volleyball team has been very successful, setting district records and making playoffs many times." - Who says they're very successful and what does that actually mean? Which district records? How many times? 
 :* "get better and better every time", "has a bright future ahead" - definite POV 
 :I'll put the POV tag back, and someone can remove it when these are gone. (I list them rather than fix, since it seems like you're interested in working on the article and learning more about Wikipedia). )
