IELTS Diagram: Introduction and Overview

For an IELTS diagram, you need an introduction and overall paragraph containing the main features of the diagram or process in your report. The overview is one of the most important parts of your report if you are aiming for band score 6 and above. See below for an example of how to write the introduction and overview for the process shown in the picture.

The site uses images to explain objects.

Introduction and Overview

  • paraphrase the information given about the diagram for the introduction
  • choose the main stages for the overview ( eggs, water, tadpole, land, adult frogs)
Model Introduction and Overview
The diagram illustrates the different stages involved in the life of a frog. Overall, tadpoles, which emerge from eggs in the water, pass through a number of phases before going on to land and maturing into adult frogs.

    The diagram illustrate how frog grows up during different stages of life cycle from an egg to adult frog.

    please let me know this intro is enough & also highlight mistakes.

    • Dont’ forget “illustrates” with an “s”. Also animals don’t “grow up”, only children grow up. Always tried to avoid errors in grammar and vocab.

  2. Dear Liz

    Could you please read my writing and tell where i’ve made mistakes and the improvement that could be made?And also how much I would score with a writing like this. It would really help me. Thanks

    The diagram depicts several stages that are involved in the Life Cycle of a frog from the stage of it being an egg, to the time it becomes an adult frog. Altogether there are 4 stages in its life cycle.

    The cycle begins from first stage where an adult frog lays eggs. The egg then grows to become what we call the embryo in the second stage which further in the stage three becomes a tadpole. A significant growth of the tadpole can be seen in this stage where its legs break through, gradually its pulmonary breathing starts .
    Its not until the third stage that the tadpole frog is out of the water and starts its life by adapting to its new environment that is the land.
    And finally in the stage four , this tadpole frog becomes an adult frog. The cycle continues in a circle.

  3. Hello Liz,

    I chanced upon your website and I would be happy to receive your comment on the introduction and overview for the Life Cycle of a Frog:

    The diagram illustrates the different stages that a frog undergoes in its life span. Clearly we see its growth from an egg and gradually developing into a tadpole until it becomes an adult frog.

    • Try to avoid “we will see …”. Avoid using “we”. Make sure your overview is easy to find: Overall, …

      • Thank you for the immediate feedback, Liz. You really are a big help. To rephrase, will this do:

        “The diagram illustrates the different stages that a frog undergoes in its life span. Overall it shows the growth and development from an egg as it gradually transitions into a tadpole until it becomes an adult frog.”

  4. Dear miss liz,
    Sorry, maybe this topic was so late. Because, to be honest, I have just visited your website and these last 3 months I have been struggling by my self. But, let me convey my ideas. I promise, this will only be introduction and overview matters due to some data problems. And As you said it is crucial to give us a high score in writing task 1. Please give me comment.

    ” The diagram illustrates a life phases of a frog as a whole. Overall, it can be seen that life cycle of a frog begins from eggs which is water as its habitant. And then, Before being a tadpole which in the next stage, land as its place to live and finally, developing to be an adult frog “

    • You’ve got all the right techniques but with so many grammar mistakes with it will seriously affect your score. I’m telling you this, not to make you unhappy, but so that you can fix your problems before your test and get a higher score. See my list of errors:
      a life phases = the life phases (you MUST learn when to use “the” and when to use “a”
      as a whole = you are adding extra words to sound good or because you think the intro is too short. Don’t do this. It is a short intro – fine.
      that life cycle = that the life cycle (problems with “the”
      which is = which are (eggs is a plural word)
      as its habitant = I’m sure when you wrote this that you were not sure if this was right or wrong. So, don’t use it. Avoid errors at all costs. Just write that the …begins from eggs which are in water.
      And = never start a sentence with “and” this is a common error which the examiner will look for. “and” is a conjunction in the middle of two sentences. So, in this case, just start your sentence with “Then”
      ” Before being a tadpole which in the next stage, land as its place to live and finally, developing to be an adult frog “” this whole sentence is grammatically incorrect. Kept your information easy to read. “Before becoming a tadpole, moving onto land and developing into an adult frog.” I gave three stages clearly in order. This is your overview – no need for linking words – use them in your body paragraph.

      I hope this list will help you develop. Here is a list of tips:
      1. Keep your information easy to read
      2. be careful with “the” or “a”
      3. be careful with plural nouns and third person verbs eggs = are
      4. don’t make your sentences so long and don’t pack sentences with too much information. Keep things clear and easy to read.
      5. don’t use “and” or “but” or “because” at the beginning of sentences. See my linking words on the main writing task 1 and 2 pages.
      6. Aim to reduce errors. Don’t try to impress the examiner – just keep your errors down. More errors = lower score!!

      Good luck!!

  5. How about this introduction for the diagram. “This diagram illustrates the life events occurring in the development of eggs into mature adult frog.”

  6. Hello Liz. For the diagram do we need to have a conclusion or not?

  7. hi liz
    i am sajid form india l love your lectures,model paper as well as practice paper they are really very helpful for me keep it up liz you are doing job may god bless you

  8. hi liz
    is this type of graphs(diagram ) often come in ielts
    because quit hard

  9. Hello Liz
    Is it important to always have an overview??
    I’ve read many task 1 samples of maps and line graph with pie chart combined in one task without an overview
    I’m confused as when i should have them

  10. Dear Liz,

    Do you think this type of overview is correct? ” Overall, it takes six stages (listing all the stages) starting from eggs and finishing with adult frog.”

  11. You are so great!Thanks a lot.

  12. its great….

  13. Dear Liz,
    thanks a lot, a big like to you 🙂

  14. Hi Liz,

    did this question come out last year on oct-november?

  15. Dear liz, thanks for ur helpful guideline. Liz I need a model answer for frog life cycle. Can u provide me this model answer?

  16. Hello
    I have prepared myself for a long time but I think that my english is quite bad and the mostly I am afraid to get less than 6.5.
    I think that I’ll have the most problem with listening part and also with these diagrams . It’s looks so complicated and rare.
    My test date is in Dececember 5th.
    How I can make better my listening .?
    Always I was bad with that.
    What You could advice me to get band 6.5 ?
    Thank You for Your time .

  17. is one sentence for the introduction enough? or do i still have to make a 2 sentence introduction?

    • One sentence is enough for an introduction for task 1. This is not an essay. You can put your overview with the introduction (which means two or three sentences) or in a separate paragraph.

  18. Dear Liz,
    Thank you for your great support on our path to success.

  19. Elizabeth kasamn says:

    Hello miss Liz ,
    it would be a great help if you take a look .

    the diagram illustrates the development stages of the frog’s life cycle. Overall, the life cycle of a frog is a natural process which improves in six tips , which are ( eggs, embryo , tadpole, legs , land to adult frog ) , it begins with eggs’ production and ends with being adult frog.

  20. Noha Faisal says:

    Hi Liz,
    Can i write (at the first glance ) in IELTS writing task 1 ? or it is considered as a speaking language more ?

    • “At first glance” means that you are looking quickly without thinking much. That is completely the wrong information to give when your task is to analyse the chart or graph deeply. So, don’t use it.
      All the best

  21. Hi Liz,
    I stubbled upon your website this afternoon and its so nice to have a very active kelt tutor that responds to every comment from her subscribers.please kindly go through my essay and let me know how I did.

    The diagram demonstrates the different phases in life of a frog. In overall, there are 6 main stages starting from egg and to the final stage of adult frog. And the whole process takes place inside water and on water surface.
    The initial process begins with many eggs being laid inside water, which eventually gets into embryo and embryo develops into tadpole. There are 2 stages of a tadpole, but from the second stage which is slightly longer in length, it starts developing legs. As soon as the front legs are developed, the next phase is the start of pulmonary breathing .
    From the moment the tadpole start breathing through the lungs,it jumps unto the water surface and becomes a tadpole frog. And from tadpole frog, it develops into an adult frog. The life cycle then starts again with the adult frog laying it’s eggs inside water.

    Total of 146 words.(tried to makeup the remaining 4 words but my 20mins is up)
    Please can you grade it for me. I tried to write it as if am in exam although I know if I am in exam I will get extra time from task 2.

  22. dear liz,
    Thank you very much, you are really doing a good work on your website.I will like to write my introductory passage.
    The diagram illustrate the developmental stages of a frog from its egg to an adult frog.

  23. Haneen Alhroub says:

    Dear Liz
    I want you to check my writing please (:

    This diagram demonstrates one of the ecological systems in which a sequence of a frog’s life. Overall, it consists of three main stages starting with embryos getting out from the eggs, tadpoles growing and then leaving the water to the land to be an adult frog.

    First of all, the frog female put its eggs inside the water and left them. After a period of time, the eggs hatch to release the embryos which in turn develop to tadpoles. Secondly, tadpoles enter several phases to be ready for land life adaptation, through the time, the front legs appear, and then followed by changes in breathing pattern where the tadpoles start to breath for the first time by their lungs. Finally, the tadpoles frog transfer to live at the land, its back legs grow during this phase to become a mature adult frog which it can depend on itself to continue its life and repeat the cycle again.

    Dear Liz,
    Thank you for your very helpful lessons. I find process difficult to meet the word-numbers requirement. I always have to manage to add more words after finishing the task. After some attempts, i came up with this writing. I would be very grateful if you could have a look at it and give me a feedback. Once again, thank you !

    The diagram provided illustrates a series of changes of a frog in it’s life cycle. There are four main stages in this cycle beginning with frog’s spawning. After that, the eggs hatch into embryos, grow into tadpoles, and then develop into froglets before becoming adult frogs
    At the beginning of the cycle, eggs are laid in the water, and then embryos emerge from the eggs. After that, the embryo develops and becomes a tadpole. It then gets through some changes, and becomes longer before it’s front legs break through.
    The cycle then continues with the start of the tadpole’s pulmonary breathing, and also it has four legs which helps it go on to land. At the next stage, the creature develops into a tadpole frog before turning into an adult frog at the end of the process. This means the full growth cycle is completed, and the frog then starts the whole process again.

  25. Hi liz! Im really grateful for your posts and your truly an angel to all of us whose in the battle for this IELTS exam.Thank you so much for having such kindness of nurturing and making our dreams imminent

  26. Dear Liz,
    I am so grateful for having stumbled upon your website. It came as such a big help for me. I would be really happy if you could read my sample answer on this diagram and give me some feedback and if possible a score. This would be my first feedback,because I chose to prepare on my own for the exam, which will be on the 18th of april, so I will for real be immensely grateful for your feedback.

    This diagram represents the different stages of a life cycle of a frog.
    Overall, the frog’s life starts in the form of eggs, goes through a few more different stages and ends with a fully developed frog.
    The existence of the frog begins as eggs, which are located in grass, underwater. Then, the second stage is the formation of an embryo, which is then followed by three consecutive stages in which a tadpole is steadily formed. A change occurs in the next stage in which the tadpole’s shape is alternated by the appearance of legs.
    The following and last three stages occur mostly on land. After it has received front legs, the tadpole creates a second pair of legs, this time on the back. Then, it starts a pulmonary breathing, thus escaping its underwater habitant and reaching the land. Once it is there, the tadpole evolves into a tadpole frog which then reaches the final stage of evolution – an adult frog.

    word count: 161

    • It’s good. However, work a bit more on your overview. Either give the number of stages or summarise the main stages rather than only stating ” a few more different stages” – be clearer. The overview is very important to get right.
      All the best

  27. Hi Liz,
    It would be great if you take a look at this.

    The diagram shows the life events of an adult frog. Overall, it started from an eggs in the water that hatched to a tadpoles which transformed through a different phases of life by the water until finally reaching on to land and evolved into a matured frog.

    • You have the right content but there are problems with grammar and vocabulary. “life events” isn’t appropriate for an animal. You need to use either life cycle or “stages in the life of…”. Don’t take chance with paraphrasing. The more mistakes you make, the lower your score will be.

      For grammar, be careful of “an eggs” – it can’t be plural and singular at the same time. Also, the report should be in the present tense if there is no date on it, so you can’t have “it started…”.
      A good try.

      • Thanks Liz but can I give it one more try?

        The diagram illustrates the different stages of how to become an adult frog. Overall, tadpoles, which hatch from eggs, go through a phases of life by the water until finally ready to go to land and transform into a matured frog.

        • The overview is better but your language is still a problem for the introduction. The diagram does not show “how to become an adult frog” – it isn’t something we can learn and do ourselves. Keep your language accurate “The diagrams illustrates the stages in the life of a frog”.
