PREAMBLE: A student is writing an article for the school newspaper about planning for graduation. Read the draft of the article and complete the task that follows. STIMULUS: Graduating teens have varied options such as entering the work force, enrolling in a tech/vocational program, completing a trade apprenticeship, enlisting in the military, or attending a community college or a four-year university. If you are interested in attending college or enlisting in the military, planning is essential: For those considering the military, a high school diploma is necessary and one must be a United States citizen, S/he also must take the Armed Services Vocational Aptitude Battery or ASVAB test and must achieve the required score for your branch of service. The ASVAB test will be given at out school in October, so check with the counselor to sign up in advance. For community colleges in the State of Washington, a student must take the Compass Test and pass the math, reading and writing sections. If oarticle. of the Compass test is not met, the student will need to retake the test. These tests are given at many sites often--call the local community college to save your date and time. For those students who are interested in four year colleges, like Western or Washington State University, a student must take the SAT or ACT. it is offered multiple times throughout the school year. To sit for these tests, register at collegeboard.org or act.org. You may also get information from your school counselor. It is hard to believe that in little less than a year, we will not be going to this school or possibly even living in this city. Sitting among our friends, listening to our teachers, and cheering at the events, we still hear, a little nagging voice asking, "What will you be doing at this time next year? " That question is urging us to make the necessary preparations for our future plans. After all, we are the ones in charge. PROMPT: Write an introduction that introduces the topic and main subtopics of the article.

From what I can see, you are looking for an introduction that introduces the topic and subtopics of the article.
Among other things, this section will depend upon your main takeaway for the article. From your prompt, it looks like you want to discuss continuing education options for high school graduates. The prompt lists five options.
1) Graduates entering the workforce immediately after graduation
2) Graduates enrolling in a tech/vocational program
3) Graduates completing a trade apprenticeship
4) Graduates enlisting in the military
5) Graduates attending a community college or four-year university.
Before we get into an introduction, I highly suggest a working title. This will help in solidifying the focus of the article. Here are some recommendations:

The Busy High Schooler's Guide to Continuing Education
Post-Secondary Options for the Smart High Schooler
The X Best Life Options After High School
What Every High Schooler Should Know About College and the Military

So, the above are just some ideas. Now, we want to write an introduction. Below, I present some suggestions for writing this very important section. Before we begin, however, I want to stress that the best intros always present a problem and likely solutions to that problem. So, we want to dedicate about one to three sentences to the problem and why it's important. We also want to write another one to three sentences briefly outlining the available solutions.
a) Begin the introduction with a short but attention-grabbing sentence. For example:

Some seniors think graduation is the gateway to eternal video-game marathons.
I know what you're thinking: You'll sooner join the circus than go to college.
Should graduates join the military or go to college? Does it matter?

So, the above are just some ideas for the first line. Be creative and come up with an attention-grabbing sentence. You'll be surprised at how effective it is in getting your readers' attention.
b) Now, we want to lay out the problem: What should high schoolers do after graduation? There is an array of options, and each is as valid as the next. Briefly explain why it's important for high school graduates to make an informed career decision: their success and happiness in life depends upon the choices they make. Of course, career paths can change; the important thing is to move forward with actionable plans.
c) Next, we want to present some solutions, such as vocational school, community college, the military, and so on. After doing so, include some important statistics. Don't overdo it (remember that this is the introduction). Two links that may help:
National Center For Education Statistics (some information for the 2019 school year may not be available).
Bureau of Labor Statistics
So, the above would constitute the introductory section for your essay. For the rest of the essay, here are a few points worth considering:

To join the military, students will need a high school diploma and ASVAB scores. Talk about base scores needed for each branch of the military. What about special forces? Military schools are also an option.
For college, talk about 2+2 programs (two years at a community college and the last two at a four-year institution). You can also discuss associate's and bachelor's degrees. Explore what public and private schools offer students.
For vocational programs, talk about the choices available for students. There are programs to train as machinists, plumbers, welders, and electricians.
If high school graduates want to explore job options, what are some jobs that require only a high school diploma? Here are some ideas: Highest Paying Jobs For High School Graduates.
