Why 2020 Is A Critical Global Tipping Point For Social Media

This year is likely the last one ever in which you can say that more than half the planet is not on social media.

Hootsuite just released a massive digital state of the union report. Some of the high-level findings:

5.2 billion of us now have phones globally
4.5 billion are connected to the internet
3.8 billion are active social media users

That 3.8 billion is 49% of the planets population, and it grew 9% over the past year. That means it is extremely likely that sometime this calendar year, more than half of all of us will be active social media users.

After SAT and ACT Cancel, Registrations Soar for Classical Education Exam

An alternative college admissions test, used by some Christian schools, draws a record 50,000 students.

The Classic Learning Test (CLT), a niche college entrance exam aspiring to bring a sense of virtue to standardized tests, saw a 1,000 percent increase in registrations over its short history when the SAT and ACT canceled testing for the remainder of the school year due to COVID-19.

“Because we are able to administer the test remotely, we’re kind of the only game in town,” said Jeremy Tate, who created the CLT four years ago amid a renaissance in Classical education, including among Christians.

At its first administration in June 2016, 47 students took the CLT. With the bump in registration, 50,000 students will take its suite of tests—the CLT, and the CLT-8 and CLT-10, designed for lower grades—during the 2019-2020 academic year. That’s more than double last year’s total.

Though not a Christian company, CLT references figures including John Henry Newman and C. S. Lewis in its promotional materials and stresses the moral, formational dimension to education. The exam has been popular among classical Christian schools, which educate over 40,000 students in the US, and homeschoolers, who make up about 40 percent of CLT test-takers.

So far, 178 colleges and universities in the US accept the exam, mostly Catholic and Protestant schools. For other institutions, the CLT can serve as a supplemental assessment.

The College Board and ACT Inc., the companies that administer the SAT and ACT, respectively, have canceled or postponed in-person testing until the fall, leading many colleges to make the admissions exams an optional part of their applications. In 2018, around 2 million students took the SAT and 1.9 million took the ACT.

While some registrants may turn to the CLT this year for the convenience ...
