Use Your Summer to Switch Careers: How to Get IT-Ready in 90 Days

Summer doesn’t have to mean stagnation. While most people are waiting for “the right time” to make a career change, the smartest career changers are using the next 90 days to build the skills, credentials, and confidence to land a job in IT or cybersecurity.

The good news? You don’t need a four-year degree, years of experience, or a massive budget to break into tech. What you do need is a plan, and 90 days is enough time to build one and execute it.

Here’s how to do it.

Why Summer Is the Best Time to Switch Careers Into IT

Summer is uniquely positioned for career changers. Kids are out of school, work schedules slow down, and the mental bandwidth that usually goes toward year-round obligations opens up. That psychological space matters more than people realize when you’re trying to learn something new.

More practically, many IT and cybersecurity programs, including accelerated bootcamps and degree programs, have summer start dates. Employers in tech also tend to ramp up hiring in Q3 and Q4, which means a summer start positions you to hit the job market at exactly the right moment.

The 90-day window aligns with several entry-level certification timelines. CompTIA A+, CompTIA Security+, and CompTIA Network+ are all achievable within three months for a focused, motivated learner. These certifications are the hiring benchmarks for roles like help desk technician, IT support specialist, and junior cybersecurity analyst and they carry real weight with employers.

What “IT-Ready” Actually Means in 90 Days

Let’s set realistic expectations. In 90 days, you’re not going to become a senior network engineer or a CISO. But “IT-ready” genuinely employable, credentialed, and competitive for entry-level roles is absolutely within reach.

By the end of 90 days, a focused career changer should be able to:

• Hold at least one industry-recognized certification (CompTIA A+ or Security+)
• Understand foundational networking, hardware, and operating system concepts
• Speak to basic cybersecurity principles in a job interview
• Apply for entry-level roles including help desk, IT support, and SOC Tier 1 analyst positions

That’s not a fantasy timeline. That’s the result of a structured, intentional 90-day effort.

The 90-Day IT Career Switch Plan

Days 1–30: Build Your Foundation

The first month is about getting oriented and building the technical vocabulary that everything else depends on.

What to focus on:

• Computer hardware basics (how processors, RAM, storage, and peripherals work)
• Operating systems fundamentals (Windows, basic Linux navigation)
• Networking concepts (IP addressing, DNS, DHCP, basic protocols)
• Introduction to cybersecurity principles (CIA triad, common threats, basic defenses)

Certification target for this phase: CompTIA A+ (Core 1 — hardware and networking)

If you’re enrolled in an accelerated program, your coursework during this phase will map directly to A+ exam domains. If you’re self-studying, allocate 2–3 hours per day and use a combination of Professor Messer’s free study guides, CompTIA’s CertMaster Learn, and hands-on labs wherever possible.

Milestone check at Day 30: Can you explain what happens when a computer boots up? Can you identify the OSI model layers? Can you define what a firewall does? If yes, you’re on track.

Days 31–60: Go Deeper and Get Hands-On

Month two is where the work gets more interesting — and more valuable to employers.

What to focus on:

• Network+ level topics: routing, switching, wireless networking, network troubleshooting
• Security fundamentals: vulnerability types, authentication, encryption basics, security tools
• Hands-on lab work: setting up virtual machines, practicing network configurations, running basic scans

Certification target for this phase: CompTIA A+ Core 2 (operating systems, security, software troubleshooting) or CompTIA Network+

This is the phase where many self-learners stall. The material gets denser, and without structure, it’s easy to lose momentum. This is one of the strongest arguments for enrolling in a structured program rather than going it alone — accountability, instructor access, and a defined curriculum keep you moving when motivation dips.

Milestone check at Day 60: Schedule and sit for your first certification exam. Even if you don’t pass on the first attempt, the experience of taking the exam is valuable. (Note: some programs offer unlimited exam retake support, which removes much of the financial risk from attempting early.)

Days 61–90: Specialize, Certify, and Start Applying

The final 30 days are about narrowing your focus, stacking credentials, and beginning your job search.

What to focus on:

• Pick a lane: cybersecurity, networking, cloud, or IT support
• Pursue a specialization certification: CompTIA Security+ for cybersecurity, CompTIA Network+ for networking, or AWS Cloud Practitioner for cloud
• Build a simple resume and LinkedIn profile that leads with your certifications
• Begin applying for entry-level roles and reaching out to IT professionals in your target field

Why certifications matter so much at this stage: In IT and cybersecurity, certifications are the currency of the entry-level job market. Unlike most industries where experience alone opens doors, tech has a robust credentialing infrastructure that allows career changers to demonstrate competency without years of work history. A CompTIA Security+ certification, for example, satisfies DoD 8570/8140 requirements — meaning it qualifies you for entry-level roles at defense contractors and government agencies, a significant employer category in markets like San Diego.

Milestone check at Day 90: You should have at least one certification in hand, a polished resume, and 10–20 job applications submitted. That’s a realistic 90-day outcome.

What Kind of Program Should You Enroll In?

The 90-day timeline is achievable solo, but it’s significantly more reliable with a structured program behind you. Here’s how the main options compare:

For a true 90-day sprint, a focused bootcamp sequence is often the fastest path to that first certification. But if your goal is a sustainable, long-term IT career with room to grow into senior roles, a degree program that bundles certifications into the curriculum gives you far more return on your investment.

Option	Time to Job-Ready	Cost Range	Best For
Self-study only	6–12+ months	$200–$1,000	Highly self-directed learners
Certification bootcamp	1–5 days per cert	$500–$3,000	Targeted exam prep, current IT workers
Degree + certification program	12–24 months	$15,000–$40,000+	Long-term career building, maximum credential stack
Accelerated degree program	12–18 months	Varies	Career changers who want full credentials fast

San Diego Career Changers: You Have a Geographic Advantage

If you’re making this switch in San Diego, you’re doing it in one of the best markets in the country for entry-level IT and cybersecurity talent.

The region is home to a dense cluster of defense contractors — General Dynamics, Leidos, SAIC, Booz Allen Hamilton, Northrop Grumman — all of whom actively hire IT and cybersecurity professionals at the entry and mid levels. Many of these roles require DoD 8570/8140 compliance certifications like CompTIA Security+, which means your 90-day certification target directly maps to a real employer requirement in your backyard.

San Diego’s tech sector beyond defense is also growing, with healthcare IT, biotech, and SaaS companies expanding their technical headcount. Entry-level IT salaries in San Diego typically range from $45,000–$65,000 for help desk and support roles, with cybersecurity roles starting closer to $65,000–$85,000.

Is a 90-Day Career Switch Right for You?

This timeline works best for people who:

• Can commit 2–4 hours per day to studying
• Have some baseline comfort with computers (you don’t need to be technical, but you shouldn’t be starting from absolute zero)
• Are motivated by a specific outcome — a role, a salary target, a life change
• Have access to a structured program, accountability system, or cohort

It’s a harder path for people who are dabbling casually or treating it as a “side project.” Career switching into IT takes real effort. The 90-day timeline is aggressive by design — because the job market rewards people who move with urgency.

How CIAT Fits Into the 90-Day Plan

The California Institute of Applied Technology offers accelerated programs in IT, cybersecurity, networking, and software development — with industry certifications bundled into the curriculum. Students graduate with both an accredited degree and the credentials employers expect at the entry level, including CompTIA certifications, Cisco credentials, and others depending on the program.

For career changers who want to move fast but build something durable, CIAT’s model is designed for exactly that. Small class sizes mean you get actual instructor attention — not a 300-person lecture hall. And CIAT’s unlimited exam retake policy (with limited exceptions) means a failed first attempt doesn’t cost you extra out of pocket.

For veterans using the GI Bill, CIAT is VA-approved and participates in the Yellow Ribbon Program, making it a particularly strong option for transitioning service members looking to parlay military technical experience into civilian IT careers.
