The Google TensorFlow Certified Developer Exam is a certification assessment that tests a developer's foundational knowledge of integrating machine learning into tools and applications. It certifies your understanding of building TensorFlow models using Computer Vision, Convolutional Neural Networks, Natural Language Processing, and real-world image data and strategies[2][7].

The exam is an online performance-based test where you are provided with questions to solve by building TensorFlow models within a dedicated PyCharm environment[8]. It is open book, meaning you can use all the resources you need throughout the exam[5].
The TensorFlow Developer Certificate program aims to provide everyone in the world the opportunity to showcase their expertise in machine learning in an increasingly AI-driven global job market. This certificate in TensorFlow development is intended as a foundational certificate for students, developers, and data scientists who want to demonstrate practical machine learning skills through the building and training of models using TensorFlow[2].
The certificate program requires an understanding of the following areas:
- Foundational principles of machine learning and deep learning - How to program in Python, resolve Python issues, and compile and run Python programs in PyCharm - How to find information about TensorFlow APIs, including how to find guides and API references on tensorflow.org - How to debug, investigate, and solve error messages from the TensorFlow API - How to search beyond tensorflow.org, as and when necessary, to solve your TensorFlow questions - How to create machine learning models using TensorFlow where the model size is reasonable for the problem being solved - How to save machine learning models and check the model file size[4].
If you don't have the background above, you can take the DeepLearning.AI TensorFlow Developer Professional Certificate specialization on Coursera or the Intro to TensorFlow for Deep Learning course on Udacity to prepare for the exam[2].

Here's a simple complete proof of concept TensorFlow project that you can use as a starting point for your lab workbook:

Project: TensorFlow Image Classifier

Goal: Build a simple image classification model using TensorFlow that can classify images into one of three categories (cats, dogs, and birds).
Features:
1. Load and preprocess images using TensorFlow's intuitive API. 2. Build and optimize a simple neural network model using TensorFlow's `tf.keras` module. 3. Train the model using a small dataset of labeled images. 4. Use the trained model to classify new images and display the predictions.
Prerequisites:
1. Install TensorFlow and Python (version 3.x). 2. Have basic knowledge of Python data structures (lists, dictionaries, etc.). 3. Understand basic concepts of machine learning and neural networks.
Step 1: Data collection and preprocessing
* Collect a small dataset of images of cats, dogs, and birds (around 100-200 images per class). * Split the dataset into training, validation, and testing sets (e.g., 80% for training, 10% for validation, and 10% for testing). * Preprocess the images by resizing them to a fixed size (e.g., 224x224 pixels) and normalizing the pixel values.
Step 2: Building the model
* Create a simple neural network model using TensorFlow's `tf.keras` module. * Define the model architecture using the `tf.keras.models.Sequential` API. * Add layers for the input, convolutional layers, pooling layers, and fully connected layers. * Define the loss function and optimizer for training the model.
Step 3: Training the model
* Train the model on the training set using the `tf.keras.optimizers.AdamOptimizer` optimizer. * Monitor the model's performance on the validation set. * Fine-tune the model as needed by adjusting the hyperparameters.
Step 4: Deploying the model
* Use the trained model to classify new images. * Display the predictions and accuracy of the model.
Lab Workbook:

Step 2: Building the Model
* Show students how to define the neural network model using the `tf.keras.models.Sequential` API. * Guide students through the process of adding layers and defining the model architecture. * Ask students to implement the code to build the model.
Step 3: Training the Model
