We all love to level up our skills. Personal growth is so deeply baked into our motivations that game designers use reaching a higher level as an addictive element of their games. The desire to be more, to be better tomorrow than we are today, is one of life's most motivating drivers. In the early 1930s, a psychologist named Lev Vygotsky developed an idea that changed how we understand personal growth.
His concept, the Zone of Proximal Development (ZPD), is so simple that the first time I heard it I had an "aha" moment. It made so much sense that I couldn't believe I hadn't been using it deliberately before. The elevator pitch goes something like this: everyone has an upper limit where their current skills are no longer enough to complete a task successfully on their own. The area just above your current ability is your zone of proximal development.
Working in this zone is hard. To get the most growth, and truly level up your skills (or someone else's), two things are critical:
- Challenging opportunities inside your zone of proximal development.
- A great mentor to provide support while you operate there. Vygotsky called this scaffolding.
Once you've learned to find a ZPD, whether your own or someone else's if you're a mentor or teacher, you need to build the right scaffolding to get the most out of it.
Learner's ZPD
Mentor's ZPD
In my experience, this zone is especially easy to find when working with young children in a public school setting. You give a student increasingly challenging tasks until they start to struggle. Then you keep increasing the challenge until they reach a frustration level. The area where they're challenged but still below frustration is their zone of proximal development. The closer they get to the frustration line, the harder the task is, and the more critical it becomes to have great scaffolding in place.
Finding an adult's zone is a little harder. We learn to hide our struggles better than children do. Finding your own ZPD is harder still, because most of us don't like to admit that a failure was our fault, or that we're not yet capable of something.
Let's look at two real examples, one from home and one from work.
The piano
My children have all taken piano lessons, and every one of them struggled at first. Practicing was hard and the results didn't sound great. When it was new, their frustration level sat very close to their ability level. When those two lines are close together, the ZPD is tiny. A great teacher recognizes this and provides extra support: lessons start with only a few keys, every note is the same length, and the patterns repeat often. That simplification is scaffolding while they learn the basics.
As my children improved, their frustration level moved further from their ability level, which widened their ZPD. That extra room allowed for bigger challenges before frustration set in, which translated into faster improvement. A skilled teacher was essential to providing the right structure for guided growth.
The new hire
The same pattern shows up at work. A software engineer fresh out of school, or a sales manager leading a team for the first time, needs support to succeed. Any time we step into something new or hard, we're entering our ZPD. When that happens without mentors and leaders providing scaffolding, the company is setting the employee up to fail. A leader who takes the time to understand where an employee's ZPD sits can empower that person to build a rich, deep skill set. Identifying someone's ZPD and providing scaffolding is a win for both the employee and the company. Both end up in a stronger position.
My own zone
When I began moving into engineering leadership roles, I had plenty of room to improve. Just like my kids at the piano, my ZPD was small at first. I needed to build the basics, and having great mentors and models to follow was an important step. Early on, that support came from a lot of places: leaders at work, leaders at church, and books on the subject. I still have a lot to learn, but my ZPD has expanded. Reading books and getting generic advice isn't enough scaffolding anymore. The challenges I face now are in a completely different class than the ones I faced early on. Fortunately, I've found a couple of great mentors who provide guidance and structure. When I make a misstep, they review the situation with me and talk through what went wrong. Scaffolding goes in, and I move forward, working at a higher level than I could before.
A guide for leveling up
Every situation is different, but a few steps work as a guide whenever you want to level up a skill:
- Take time to find where your ZPD is, and how far it is from where you want to be. This takes research and honesty, but it's worth the effort.
- Find a teacher or mentor who is already above your level, and discuss what kind of intentional practice you can start doing.
- Learn to recognize frustration and take a step back. When you feel it, reach back out to your mentor for guidance.
- Be open about your mistakes. When something goes wrong, you'll naturally look for others to blame. Instead, review the part you played and ask your mentor for help.
- Periodically review your progress and adjust your goals and your ZPD as needed.
- As you level up, look for others who need a caring mentor, and be one.
We grow the most, and find the greatest rewards, when we work through hard things.
Working in your ZPD doesn't happen by accident. Taking advantage of opportunities in this zone is hard. It's draining, and sometimes overwhelming, to work above your natural skill level. But like most things in life, the growth is on the other side of the discomfort.
