Q: With a daughter entering kindergarten, and a son not far behind, we recently bought a house near a school loved by parents and hyped by the real estate agent. When we started house hunting, the school had a rating of 9 on GreatSchools.org. The website now rates it a 7. Parents still like the school, and our daughter seems happy, but should we worry?

A: Do some digging and ask questions before you put this on your worry list. In most states, GreatSchools compiles a rating using publically available data that reflects how well students do on standardized tests compared to other students in the state. The rating is on a 1-to-10 scale, where 10 is the highest, 1 the lowest.

"While test results give you a good sense of how well students are performing at a given school, they only offer a limited snapshot of school quality," says Mike Gallaher, a senior analyst at GreatSchools.org.

That's why a growing number of states are making more data available to parents, such as attendance, information on how much students learn in a given year, how prepared they are for college work or an assessment of the school's learning climate.

GreatSchools is currently focused on three aspects of academic quality, says Gallaher: "One is student achievement -- how well students at a school do in academics, measured as the percent of students meeting state standards based on state standardized tests."

No. 2 is student growth -- how much students are actually learning in a year, rather than how much they already know.

"A school with high growth could be a school with students that started behind grade level and have now caught up," notes Gallaher.

No. 3 is college readiness. "With high schools," says Gallaher, "we look at school graduation rates and performance and participation on college entrance exams (such as the SAT and ACT) as indicators of how well students are prepared for life after high school in college or careers."

Schools in states that have rolled out the Common Core State Standards (CCSS) and are testing children on those standards may see a drop in their GreatSchools rating if the tests and instruction aren't yet closely aligned.

"This is worth asking," says Gallaher. Other things to ask: What measures does the school use to track academic progress if not state tests? Has there been a change in leadership? Is there high faculty turnover? Is there any change in the student population, with new students needing extra support to catch up? What is the school's rating history?

Look at other factors, too, such as parent and community comments, what programs the school offers that are important to you, such as arts, music, after-school enrichment and so on.

"Take this opportunity to walk through all the data with the principal," suggests Gallaher. "At GreatSchools, we're willing to answer questions about how a school's rating is derived."

There may be very good reasons for the drop in score, or the school's leadership may not be aware of it and will welcome your advocacy on behalf of academic excellence.

Q: One of our sons graduated college with an architecture degree in 2013 and can't find a job. It's also true for some of his friends. My younger son, a high school junior, says this is proof that he should not waste money on college. His counselor thinks he should apply, and he's considering the military. We don't want him to rack up college debt, but don't want him to be a live-at-home barista, either. Is college worth it?

A: With daily headlines about the college loan crisis and a lack of jobs that lead to careers for graduates, this is a conversation many families are having.

"You're not alone in your concerns. College is expensive and a rising number of grads aren't able to find jobs. Some have moved back home while they hunt for work," says Rob Franek, senior vice president of The Princeton Review and author of "The Best 379 Colleges, 2015 Edition" (Princeton Review, 2014).

Keep in mind, though, that statistically speaking, the time and money one spends to get a college diploma is well worth it, says Franek: "Studies show that college grads have a richer life, both literally and culturally."

Consider these facts:

-- Lifetime earnings of a person with a college degree are much higher than those of a person with only a high school diploma. Some estimates show the earnings difference can be up to $1 million more.

-- Bureau of Labor Statistics data show that the unemployment rate is far lower among college grads (currently 2.9 percent) than among job seekers with only high school diplomas (currently 5.3 percent).

-- One Centers for Disease Control and Prevention report showed that college grads have longer lives by an average of nine years.

"The good news is that the majority of college grads are finding jobs," notes Franek, "but the employment rate varies based on one's major. Grads in STEM (science, technology, engineering and math) fields are highly employable and earn the highest starting salaries. But grads in non-technical fields, such as arts and sociology, face a tougher job market with considerably lower starting salaries."

Unfortunately for your older son, the unemployment rate for architecture majors was 12.8 percent in 2013 -- a result of the recession's construction downturn.

"But encourage him to keep searching," says Franek. "The flip side is that 87 percent of grads with architecture majors have found jobs."

Entering military service in lieu of attending college is a noble decision, says Franek, "and we heartily salute all of our military personal for their service to our country. The training one gets in various branches of the service can position one very well to find employment in some occupations upon discharge. Students who attend college via ROTC programs can get the degree and the experience in exchange for years of service after they graduate.

"But, sadly, the 2013 unemployment rate for veterans in general is high (9 percent overall) and, among the youngest veterans (18-24), it was higher still (21.4 percent)."

Bottom line: A college degree, generally speaking, is more than well worth it. But choose your major -- and borrow money -- wisely.

"If you take out loans to foot the bills, don't borrow more in total over the years it takes to earn the diploma than you can expect to earn as a beginning salary when you graduate," Franek advises.

Q: Our school sends mixed messages about digital media. They warn about online safety and too much time on screens, but then send home an iPad with my third-grader to play "homework" games. I'm confused about my role as a parent in all this.

A: With today's 8- to 18-year-olds spending up to 4,000 hours a year on technology, parents have one more tough task -- rearing smart and responsible digital citizens.

"Families use technology in every aspect of life, and it's opened up a world of educational opportunities that didn't exist a decade ago," says Bill Laraway, a fifth-grade teacher at Silver Oak Elementary in San Jose, California -- in the heart of Silicon Valley. "Technology has risks and benefits, and a parent's job is to intentionally and thoughtfully teach kids the difference."

Laraway encourages parents to work with kids in four areas: focus, safety, responsibility and oversight.

"First is focus. These tools offer wonderful ways to deepen learning and expand our creative potential," says Laraway, "but they can also be distracting to students. Kids say they are 'multitasking,' but it's a myth.

"Researcher Daniel Goleman calls multitasking 'continuous partial attention,' with the brain switching quickly between tasks. It's no way for developing brains to study. Parents have to help students learn to filter out distractions, technological or otherwise, or they will have a hard time in almost every subject."

Laraway recommends Goleman's book "Focus: The Hidden Driver of Excellence" to parents who aren't convinced.

The second is safety. Have a family policy about what to post, how passwords are stored, parental controls and so on.

"Don't scare kids, but do alert them to dangers and reinforce behaviors you want kids to adopt," says Laraway. (There are great resources at commonsensemedia.org and connectsafely.org.)

Three is responsibility. "Don't preach; lead by example," Laraway urges. "Don't be a goof online. Don't post things that will come back to haunt the family. Be kind and selective with your social media presence. Follow the Golden Rule."

Last, don't be afraid to monitor and enforce your family's policies. San Francisco parent Sean Ryan, an executive at Facebook, says, "I own every game device and tablet ever created, so we don't live in a cave, but we're pretty strict about our boys' usage and we enforce it, even if I have to look at the wireless router to confirm it.

"We limit screen time -- exempting old-school Kindles. We have borrowed more than 300 books from the library using the Kindle OverDrive system. It's just awesome."

The Ryans insist that the boys use their PCs in common areas of the home, not their rooms. "We prefer that they do homework on our desktop, since it's in the open," he says.

Their 15-year-old has what Ryan calls an "ancient" iPhone and the two younger boys' phones are used just for calling.

"We love the advantages of tech," says Ryan, "but we see how it can be abused. We're in no hurry to give them unlimited access to all forms of it -- that's why they call it 'parenting' and not 'friending.'"
